# TL;DR

&gt; In the first case with `set encoding=utf-8`, you&#39;ll change the output encoding that is **shown** in the terminal. 
&gt; 
&gt; In the second case with `set fileencoding=utf-8`, you&#39;ll change the output encoding of the file that is **written**.

As stated by @Dennis, you can set them both in your ~/.vimrc if you always want to work in `utf-8`.

# More details

From the [wiki of VIM about working with unicode](http://vim.wikia.com/wiki/Working_with_Unicode)

&lt;i&gt;&quot;`encoding` sets how **vim shall represent characters internally**. Utf-8 is necessary for most flavors of Unicode.&quot;&lt;/i&gt;

&lt;i&gt;&quot;`fileencoding` sets the **encoding for a particular file** (local to buffer); :setglobal sets the default value. An empty value can also be used: it defaults to same as &#39;encoding&#39;. Or you may want to set one of the ucs encodings, It might make the same disk file bigger or smaller depending on your particular mix of characters. Also, IIUC, utf-8 is always big-endian (high bit first) while ucs can be big-endian or little-endian, so if you use it, you will probably need to set &#39;bomb&quot; (see below).&quot;&lt;/i&gt;

    set encoding=utf-8  &quot; The encoding displayed.
    set fileencoding=utf-8  &quot; The encoding written to file.

You may as well set both in your `~/.vimrc` if you always want to work with utf-8.

You can set the variable &#39;fileencodings&#39; in your .vimrc. 

&gt; This is a list of character encodings considered when starting to edit
	an existing file.  When a file is read, Vim tries to use the first
	mentioned character encoding.  If an error is detected, the next one
	in the list is tried.  When an encoding is found that works,
	&#39;fileencoding&#39; is set to it.  If all fail, &#39;fileencoding&#39; is set to
	an empty string, which means the value of &#39;encoding&#39; is used.

See `:help filencodings`

If you often work with e.g. cp1252, you can add it there:

    set fileencodings=ucs-bom,utf-8,cp1252,default,latin9

Defining a parameterless exception:

    class MyException(Exception):
        pass

When raised, is there any difference between:

    raise MyException

and

    raise MyException()

I couldn&#39;t find any; is it simply an overloaded syntax?

Is there a difference between &quot;raise exception()&quot; and &quot;raise exception&quot; without parenthesis?

Starting from scratch without any previous Jersey 1.x knowledge, I&#39;m having a hard time understanding how to setup dependency injection in my Jersey 2.0 project.

What is the difference between these two commands?

- `set encoding=utf-8` 
- `set fileencoding=utf-8`

Do I need to set both when I want to use utf-8?

Also, do I need to set fileencoding with `set` or `setglobal`?

When I use `git commit --amend` or `git rebase -i`, vim opens up for me to make changes. If I then change my mind and exit vim without making any changes, a commit is still made which shows up in `git reflog`.

How can I delete from the disk the current open file from within vim? Would be nice to also close the buffer.

I see you [can use NERDTree for that](https://stackoverflow.com/questions/10615294/nerdtree-how-to-delete-file), but I don&#39;t use this plugin.

I&#39;ve some codes copied from the Internet that have 2-space indenting and I want to change it into 4-space indenting. I wonder if there is a short vim routine to accomplish the task without having to write vim script? Here is how I&#39;m currently doing it with an HTML file:

- Record a macro
- Go to the beginning of a line
- Visual select all whitespaces until the first occurrence of &quot;&lt;&quot;
- Yank and paste all whitespaces (basically to double them)
- Replay the macro till the end of the file

In short ``qa0vt&lt;yp&lt;esc&gt;jq``

# Pitfalls:
The macro fails for a blank line or a line that doesn&#39;t start with &quot;&lt;&quot;. And I have no idea how to extend this solution to non-HTML file.

When I want the cursor to go to the end of the file (i.e. the end of the last line) in Vim, I have to type six keystrokes:

`&lt;ESC&gt;G$a` - which translates to &lt;kbd&gt;ESC&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt;&lt;kbd&gt;g&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt;&lt;kbd&gt;4&lt;/kbd&gt; + &lt;kbd&gt;a&lt;/kbd&gt; on my keyboard layout. 

How can I do this more efficiently?

I have spent plenty of time as far as I am newbie in Python.  
How could I ever decode such a URL:

    example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0


to this one in python 2.7: `example.com?title==правовая+защита`  

`url=urllib.unquote(url.encode(&quot;utf8&quot;))` is returning something very ugly.

Still no solution, any help is appreciated.

I&#39;m writing a crawler which uses Hpricot. It downloads a list of strings from some webpage, then I try to write it to the file. Something is wrong with the encoding:

    &quot;\xC3&quot; from ASCII-8BIT to UTF-8

I have items which are rendered on a webpage and printed this way: 

    D&#195;&#169;veloppement

the `str.encoding` returns `UTF-8`, so `force_encoding(&#39;UTF-8&#39;)` doesn&#39;t help. How may I convert this to readable UTF-8?

I&#39;m trying to fetch an image from the web and encode it with base64.

what i have so far is basically:

    var request = require(&#39;request&#39;);
    var BufferList = require(&#39;bufferlist&#39;).BufferList;

    bl = new BufferList(),

    request({uri:&#39;http://tinypng.org/images/example-shrunk-8cadd4c7.png&#39;,responseBodyStream: bl}, function (error, response, body) 
    {
        if (!error &amp;&amp; response.statusCode == 200) 
        {
            var type = response.headers[&quot;content-type&quot;];
            var prefix = &quot;data:&quot; + type + &quot;;base64,&quot;;
            var base64 = new Buffer(bl.toString(), &#39;binary&#39;).toString(&#39;base64&#39;);
            var data = prefix + base64;
            console.log(data);
        }
    });

This seems to be pretty close to the solution but i can&#39;t quite get it to work. It recognizes the data type and gives out the output:

    data:image/png;base64

however the bufferlist &#39;bl&#39; seems to be empty.

Thanks in advance!

Node.js get image from web and encode with base64

If I convert a  character to `byte` and then back to `char`, that character mysteriously disappears and becomes something else. How is this possible?

This is the code:

	char a = &#39;&#200;&#39;;       // line 1		
 	byte b = (byte)a;   // line 2 		
  	char c = (char)b;   // line 3
  	System.out.println((char)c + &quot; &quot; + (int)c);

Until line 2 everything is fine:

- In line 1 I could print &quot;a&quot; in the console and it would show &quot;&#200;&quot;.

- In line 2 I could print &quot;b&quot; in the console and it would show -56, that is 200 because byte is signed. And 200 is &quot;&#200;&quot;. So it&#39;s still fine.

But what&#39;s wrong in line 3? &quot;c&quot; becomes something else and the program prints `?  65480`. That&#39;s something completely different.

What I should write in line 3 in order to get the correct result?

I am trying to parse xml which contains the some non ASCII cheracter, 

the code looks like below

    from lxml import etree
    from lxml import objectify
    content = u&#39;&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;&lt;div&gt;Order date &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160;: 05/08/2013 12:24:28&lt;/div&gt;&#39;
    mail.replace(&#39;\xa0&#39;,&#39; &#39;)
    xml = etree.fromstring(mail)

but it shows me error on the line &#39;content = ...&#39;
like 

    syntaxError: Non-ASCII character &#39;\xc2&#39; in file /home/projects/ztest/responce.py on line 3, 
    but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

in the terminal it&#39;s working but while running on the eclipse IDE it&#39;s giving me a error.

Don&#39;t know how to overcome..
