It is the Line Feed character.

  [1]: http://unicodelookup.com/#&amp;amp;#10;/1


It&#39;s the ASCII character LF, Line Feed.

Some systems (e.g. Windows) use the combination CR+LF, `&amp;#13;&amp;#10;`, for line break, some systems (e.g. Linux) use only LF as line break, some systems (e.g. Macintosh) use only CR as line break.

So, only a LF character in an XML value would be a line break from a Linux system (or similar).

I know the browser shares my IP address and details of nearby wireless networks to determine my location, but what sort of info does it know about nearby wifi networks?

For example, where I live are no public wireless networks, and from my home I can see about 5 private networks, yet my location is determined within 20 meters. With there being no open networks nearby, how does Google determine my location? The only way I can think of is that Google mapped the locations of all wireless networks when they mapped streets for Street View.

I&#39;ve searched about online, but all I can&#39;t find any specific details.

Please help.
Thanks.

I&#39;ve been beating my head against this absolutely infuriating bug for the last 48 hours, so I thought I&#39;d finally throw in the towel and try asking here before I throw my laptop out the window.

I&#39;m trying to parse the response XML from a call I made to AWS SimpleDB. The response is coming back on the wire just fine; for example, it may look like:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt; 
    &lt;ListDomainsResponse xmlns=&quot;http://sdb.amazonaws.com/doc/2009-04-15/&quot;&gt;
        &lt;ListDomainsResult&gt;
            &lt;DomainName&gt;Audio&lt;/DomainName&gt;
            &lt;DomainName&gt;Course&lt;/DomainName&gt;
            &lt;DomainName&gt;DocumentContents&lt;/DomainName&gt;
            &lt;DomainName&gt;LectureSet&lt;/DomainName&gt;
            &lt;DomainName&gt;MetaData&lt;/DomainName&gt;
            &lt;DomainName&gt;Professors&lt;/DomainName&gt;
            &lt;DomainName&gt;Tag&lt;/DomainName&gt;
        &lt;/ListDomainsResult&gt;
        &lt;ResponseMetadata&gt;
            &lt;RequestId&gt;42330b4a-e134-6aec-e62a-5869ac2b4575&lt;/RequestId&gt;
            &lt;BoxUsage&gt;0.0000071759&lt;/BoxUsage&gt;
        &lt;/ResponseMetadata&gt;
    &lt;/ListDomainsResponse&gt;

I pass in this XML to a parser with 

    XMLEventReader eventReader = xmlInputFactory.createXMLEventReader(response.getContent());

and call `eventReader.nextEvent();` a bunch of times to get the data I want.

Here&#39;s the bizarre part -- it works great inside the local server. The response comes in, I parse it, everyone&#39;s happy. The problem is that when I deploy the code to Google App Engine, the outgoing request still works, and the response XML seems 100% identical and correct to me, but the response fails to parse with the following exception:

    com.amazonaws.http.HttpClient handleResponse: Unable to unmarshall response (ParseError at [row,col]:[1,1]
    Message: Content is not allowed in prolog.): &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;

I have double, triple, quadruple checked this XML for &#39;invisible characters&#39; or non-UTF8 encoded characters, etc. I looked at it byte-by-byte in an array for byte-order-marks or something of that nature. Nothing; it passes every validation test I could throw at it. Even stranger, it happens if I use a Saxon-based parser as well -- but ONLY on GAE, it always works fine in my local environment.

It makes it very hard to trace the code for problems when I can only run the debugger on an environment that works perfectly (I haven&#39;t found any good way to remotely debug on GAE). Nevertheless, using the primitive means I have, I&#39;ve tried a million approaches including:

* XML with and without the prolog
* With and without newlines
* With and without the &quot;encoding=&quot; attribute in the prolog
* Both newline styles
* With and without the chunking information present in the HTTP stream

And I&#39;ve tried most of these in multiple combinations where it made sense they would interact -- nothing! I&#39;m at my wit&#39;s end. Has anyone seen an issue like this before that can hopefully shed some light on it?

Thanks!

&quot;Content is not allowed in prolog&quot; when parsing perfectly valid XML on GAE

What I would like to achieve is the ability to &quot;dynamically&quot; (i.e. based on a property defined in a configuration file) enable/disable the importing of a child Spring XML context.

I imagine something like:

    &lt;import condition=&quot;some.property.name&quot; resource=&quot;some-context.xml&quot;/&gt;

Where the property is resolved (to a boolean) and when true the context is imported, otherwise it isn&#39;t.

Some of my research so far:

 - Writing a custom NamespaceHandler (and related classes) so I can register my own custom element in my own namespace. For example: `&lt;myns:import condition=&quot;some.property.name&quot; resource=&quot;some-context.xml&quot;/&gt;`

   The problem with this approach is that I do not want to replicate the entire resource importing logic from Spring and it isn&#39;t obvious to me what I need to delegate to to do this.
 - Overriding `DefaultBeanDefinitionDocumentReader` to extend the behaviour of the &quot;import&quot; element parsing and interpretation (which happens there in the `importBeanDefinitionResource` method). However I&#39;m not sure where I can register this extension.

I&#39;ve seen people using *.cfg (Python Buildout), *.xml (Gnome), *.json (Chrome extension), *.yaml (Google App Engine), *.ini and even *.py for app configuration files (like Django).

My question is: why there are so many different configuration file formats? I can see an advantage from a xml vs json approach (much less verbose) or a Python one (sometimes you have a Python app and don&#39;t want to use a specific module just to parse a config file), but what about the other approaches?

I know there are even more formats than those configuration files I exemplified. What are really their advantages in comparison to each other? Historical reasons? Compatibility with different systems?

If you would start an application to read some kind of configuration files (with a plugin ecosystem), which one would you use?

Which ones that I gave as example are the oldest ones? Do you know it&#39;s history?

Pros and cons for different configuration formats?

I have created a xml file using xml.etree.ElementTree in python. I then use

    tree.write(filename, &quot;UTF-8&quot;) 

to write out the document to a file.

But when I open filename using a text editor, there are no newlines between the tags. Everything is one big line

How can I write out the document in a &quot;pretty printed&quot; format so that there are new lines (and hopefully indentations etc) between all the xml tags?

I am just learning XML and how to use XSL files.
In an XSL file I found the following term:

And what could I use instead of the `/`?
Could I write `table` or any other HTML tag instead of `/`?

In Ruby on Rails 3 (currently using Beta 4), I see that when using the `form_tag` or `form_for` helpers there is a hidden field named `_snowman` with the value of ☃ ([Unicode][1] \x9731) showing up.

So, what is this for?

I&#39;m reading and parsing an Amazon XML file and while the XML file shows a &#39; , when I try to print it I get the following error:

    &#39;ascii&#39; codec can&#39;t encode character u&#39;\u2019&#39; in position 16: ordinal not in range(128) 

From what I&#39;ve read online thus far, the error is coming from the fact that the XML file is in UTF-8, but Python wants to handle it as an ASCII encoded character. Is there a simple way to make the error go away and have my program print the XML as it reads?

Python Unicode Encode Error

I am using Python 2.6.5. My code requires the use of the &quot;more than or equal to&quot; sign. Here it goes:  

    &gt;&gt;&gt; s = u&#39;\u2265&#39;
    &gt;&gt;&gt; print s
    &gt;&gt;&gt; ≥
    &gt;&gt;&gt; print &quot;{0}&quot;.format(s)
    Traceback (most recent call last):
         File &quot;&lt;input&gt;&quot;, line 1, in &lt;module&gt; 
    UnicodeEncodeError: &#39;ascii&#39; codec can&#39;t encode character u&#39;\u2265&#39;
      in position 0: ordinal not in range(128)`  

Why do I get this error? Is there a right way to do this? I need to use the `.format()` function.


Python: Using .format() on a Unicode-escaped string

I am reading about the charater set and encodings on Windows. I noticed that there are two compiler flags in Visual Studio compiler (for C++) called MBCS and UNICODE. What is the difference between them ? What I am not getting is how UTF-8 is conceptually different from a MBCS encoding ? Also, I found the following quote in [MSDN][1]:

&gt; Unicode is a 16-bit character encoding

This negates whatever I read about the Unicode. I thought unicode can be encoded with different encodings such as UTF-8 and UTF-16. Can somebody shed some more light on this confusion?

Difference between MBCS and UTF-8 on Windows

Using SQLite3 in Python, I am trying to store a compressed version of a snippet of UTF-8 HTML code.

Code looks like this:

    ...
    c = connection.cursor()
    c.execute(&#39;create table blah (cid integer primary key,html blob)&#39;)
    ...
    c.execute(&#39;insert or ignore into blah values (?, ?)&#39;,(cid, zlib.compress(html)))

At which point at get the error:

    sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

If I use &#39;text&#39; rather than &#39;blob&#39; and don&#39;t compress the HTML snippet, it works all fine (db is to large though). When I use &#39;blob&#39; and compress via Python zlib library, I get the above error message. I looked around but couldn&#39;t find a simple answer for this one.

I have a CSS file that looks fine when I open it using [gedit][1], but when it&#39;s read by PHP (to merge all the CSS files into one), this CSS has the following characters prepended to it: &#239;&#187;&#191;

PHP removes all whitespace, so a random &#239;&#187;&#191; in the middle of the code messes up the entire thing. As I mentioned, I can&#39;t actually see these characters when I open the file in gedit, so I can&#39;t remove them very easily.

I googled the problem, and there is clearly something wrong with the file encoding, which makes sense being as I&#39;ve been shifting the files around to different Linux/Windows servers via ftp and [rsync][2], with a range of text editors. I don&#39;t really know much about character encoding though, so help would be appreciated.

If it helps, the file is being saved in UTF-8 format, and gedit won&#39;t let me save it in ISO-8859-15 format (the document contains one or more characters that cannot be encoded using the specified character encoding). I tried saving it with Windows and Linux line endings, but neither helped.

In my ASP.NET application, I was trying to add few white spaces between two text boxes by typing space bar. The equivalent HTML source was `&amp;#160;` instead of `&amp;nbsp;`. So I just wanted to check: is this the new replacement for white space? If yes, any idea why they changed?


Is &quot;&amp;#160;&quot; a replacement of &quot;&amp;nbsp;&quot;?

What was the original historical use of the vertical tab character (`\v` in the C language, ASCII 11)?

Did it ever have a key on a keyboard? How did someone generate it?

Is there any language or system still in use today where the vertical tab character does something interesting and useful?


What is a vertical tab?

I&#39;m trying to parse a file in C# that has field (string) arrays separated by ASCII character codes 0, 1 and 2 (in Visual Basic 6 you can generate these by using Chr(0) or Chr(1) etc.)

I know that for character code 0 in C# you can do the following:

    char separator = &#39;\0&#39;;

But this doesn&#39;t work for character codes 1 and 2?
