I can&#39;t set &quot;UTF-8 with BOM&quot; in the corner button either, but I can change it from the menu bar.

&quot;File&quot;-&gt;&quot;Save with encoding&quot;-&gt;&quot;UTF-8 with BOM&quot;

**Into the Preferences &gt; Setting - Default**

You will have the next by default:

    // Display file encoding in the status bar
        &quot;show_encoding&quot;: false

You could change it or like cdesmetz said set your user settings.

By default, Sublime Text set `&#39;UTF8 without BOM&#39;`, but that wasn&#39;t specified.

The only specicified things is `&#39;UTF8 with BOM&#39;`.

Hope this help :)

I&#39;m trying to setup PSR-4 with Composer but I&#39;m just getting `A non-empty PSR-4 prefix must end with a namespace separator.`

My `autoload` in my `composer.json` looks like this:

    &quot;autoload&quot;: {
    	&quot;psr-4&quot;: {
    		&quot;Acme\\models&quot; : &quot;app/models&quot;
    	}
    },

`app/models` is empty.

What am I doing wrong? How can I fix this?

In above class am passing &quot;**ABC**&quot; with in **@MyAnnotation**.
Now how can i access &quot;**ABC**&quot; value in **procede** method of **SomeAspect.java** class?


Thanks!

When I open a file in Sublime Text 3, at the bottom I have an option to set the Character Encoding as shown in the screenshot.

![setting encoding][1]

There is the option to set it to **UTF-8** , which after doing some research means UTF-8 Without BOM, but I want to set it to **UTF-8 With BOM** like shown below:

Also: Is this problem solvable with javascript? Convert it before sending it ?

Mysql2::Error: Incorrect string value

I am trying to encode a text string to base64.

i tried doing this :

    name = &quot;your name&quot;
    print(&#39;encoding %s in base64 yields = %s\n&#39;%(name,name.encode(&#39;base64&#39;,&#39;strict&#39;)))

But this gives me the following error:

    LookupError: &#39;base64&#39; is not a text encoding; use codecs.encode() to handle arbitrary codecs

How do I go about doing this ? ( using Python 3.4)

While sending email content, it is required to set &quot;Content Transfer Encoding&quot; header. I observed many headers of emails that I received. Some emails using &quot;7bit&quot; and some are using &quot;8bit&quot;.

What is the difference between these two? Which is recommended? Is there any special encoding required for email body in order to set these headers?

I want to achieve Base64 URL safe encoding in C#. In Java, we have the common `Codec` library which gives me an URL safe encoded string. How can I achieve the same using C#?

    byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(&quot;StringToEncode&quot;);
    string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);

The above code converts it to Base64, but it pads `==`. Is there is way to achieve URL safe encoding?

Was reading [Joel Spolsky&#39;s &#39;The Absolute Minimum&#39; about character encoding][1].
It is my understanding that ASCII is a Code-point + Encoding scheme, and in modern times, we use Unicode as the Code-point scheme and UTF-8 as the Encoding scheme. Is this correct?

ASCII vs Unicode + UTF-8

I&#39;m trying to convert a unicode string to a hexadecimal representation in javascript.

This is what I have: 

    function convertFromHex(hex) {
        var hex = hex.toString();//force conversion
        var str = &#39;&#39;;
        for (var i = 0; i &lt; hex.length; i += 2)
            str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
        return str;
    }

    function convertToHex(str) {
        var hex = &#39;&#39;;
        for(var i=0;i&lt;str.length;i++) {
            hex += &#39;&#39;+str.charCodeAt(i).toString(16);
        }
        return hex;
    }

But if fails on unicode characters, like chinese; 

Input: 
漢字

Output: 
&#170;o&quot;[W

Any ideas? Can this be done in javascript?

After importing my project from eclipse into android studio i have got the following error : 

    Error: unmappable character for encoding UTF-8

**Android Studio** : 0.5.8
 

Android Studio : unmappable character for encoding UTF-8

I have a problem with **inconsistent encoding of character vector** in R. 

The text file which I read a table from is encoded (via `Notepad++`) in `UTF-8` (I tried with `UTF-8 without BOM`, too.). 

I want to read table from this text file, convert it do `data.table`, set a `key` and make use of binary search. When I tried to do so, the following appeared: 

&gt; Warning message:
&gt;     In `[.data.table`(poli.dt, &quot;żżonymi&quot;, mult = &quot;first&quot;) :
&gt;     A known encoding (latin1 or UTF-8) was detected in a join column. data.table compares         the bytes currently, so doesn&#39;t support
&gt; *mixed* encodings well; i.e., using both latin1 and UTF-8, or if any unknown encodings are non-ascii and some of those are marked known and
&gt; others not. But if either latin1 or UTF-8 is used exclusively, and all
&gt; unknown encodings are ascii, then the result should be ok. In future
&gt; we will check for you and avoid this warning if everything is ok. The
&gt; tricky part is doing this without impacting performance for ascii-only
&gt; cases.

and binary search **does not work**. 

I realised that my `data.table`-`key` column consists of both: &quot;unknown&quot; and &quot;UTF-8&quot; Encoding types: 

    &gt; table(Encoding(poli.dt$word))
    unknown   UTF-8 
    2061312 2739122 

I tried to convert this column (before creating a `data.table` object) with the use of: 

 * `Encoding(word) &lt;- &quot;UTF-8&quot;`
 * `word&lt;- enc2utf8(word)`

but with no effect. 

I also tried a few different ways of reading a file into R (setting all helpful parameters, e.g. `encoding = &quot;UTF-8&quot;`):

 * `data.table::fread` 
 * `utils::read.table`
 * `base::scan`
 * `colbycol::cbc.read.table`

but with no effect.

Force character vector encoding from &quot;unknown&quot; to &quot;UTF-8&quot; in R

I want to edit multiple lines and every &quot;word&quot; within that line. For example:

    45 28 42 65
    24 87 47 95
    01 25 87 98

I want to select every whole number in all lines and put a &quot;0x&quot; before it so it would look like:

    0x45 0x28 0x42 0x65
    0x24 0x87 0x47 0x95
    0x01 0x25 0x87 0x98

I know the &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;shift&lt;/kbd&gt;+&lt;kbd&gt;L&lt;/kbd&gt; to get cursors on each line, but how can I get the cursors in front of every number to mass edit all at once?

Sublime Text 3, convert spaces to tabs

Setting up sublimetext 3 as git commit text editor

I want to configure Sublime Text 3 to build Python 3, but I don&#39;t seem to understand how the builds work. Many tutorials have told me to make a build file containing code such as:

    {
        &#39;cmd&#39;: [&#39;/usr/bin/python3&#39;, &#39;-u&#39;, &#39;$file&#39;],
        &#39;file_regex&#39;: &#39;^[ ]*File &quot;(…*?)&quot;, line ([0-9]*)&#39;,
        &#39;selector&#39;: &#39;source.python&#39;
    }

and save it as a file called `Python.sublime-build` or `python3.sublime-build` (much of the information I found was conflicting). One tutorial suggested creating a new folder in the ST3 Packages folder called `Python` and add the build file in there, whilst other tutorials suggested leaving it in the folder called `User`. 

One tutorial explained how I had to change the Environment Variable `path` on my operating system to get it to work. That didn&#39;t seem to help either.

---

I added a folder `Python` to `Packages` (since it wasn&#39;t there already) and added in a build file with the name `Python.sublime_build` which featured only the code I posted above in it. Now when I attempt to run Sublime Text it gives me this error:

    Error trying to parse build system:

Sublime text 2 - how to order a list of words alphabetically (DESC / ASC)

Github announced [Atom](https://atom.io/) which is very similar to Sublime. Even some keyboard shortcuts like &lt;kbd&gt;⌘ + P&lt;/kbd&gt;, &lt;kbd&gt;⌘ + Shift + P&lt;/kbd&gt; etc. are same.  

1. How is Atom different from Sublime?  
2. Does it include IDE features like build tools, function definition jumps, documentations, etc.?
3. Has anyone using Sublime got a Beta invitation to point out the differences?
4. Can I use the themes, schemes and packages from Sublime as is, like Sublime could do with **text mate**.

What is the difference between Sublime text and Github&#39;s Atom

I&#39;m having difficulty getting this set up. I fixed my `.bash_profile`, and created the symlink using the following command from the Sublime website:

    ln -s &quot;/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl&quot; ~/bin/subl 

Yet, when I input that command I get:

    ln: /Users/my_username/bin/subl: No such file or directory

It appears my terminal is looking at the wrong place for the file? Why is it trying to point to a `bin` folder on my home directory?
