A nice, light, library which I use successfully is [utf8proc][1].

There&#39;s also [MicroUTF-8][1], but it may require login credentials to view or download the source.

UTF-8 is specially designed so that many byte-oriented string functions continue to work or only need minor modifications.

C&#39;s **`strstr`** function, for instance, will work perfectly as long as both its inputs are valid, null-terminated UTF-8 strings. **`strcpy`** works fine as long as its input string starts at a character boundary (for instance the return value of **`strstr`**).

So you may not even need a separate library!

Say I have an interface like this:

    public interface ISomeInterface
    {
    ...
    }

I also have a couple of classes implementing this interface;

    public class SomeClass : ISomeInterface
    {
    ...
    }

Now I have a WPF ListBox listing items of ISomeInterface, using a custom DataTemplate.

The databinding engine will apparently not (that I have been able to figure out) allow me to bind to interface properties - it sees that the object is a SomeClass object, and data only shows up if SomeClass should happen to have the bound property available as a non-interface property. 

How can I tell the DataTemplate to act as if every object is an ISomeInterface, and not a SomeClass etc.?

Thanks!

I feel like developers talk about memory leaks but when you ask them what that means many have no idea.  To prevent these situations, let&#39;s decide on one.

Please no Wikipedia definitions...

&gt; What is your best definition of a
&gt; **memory leak** and what is the *best way*
&gt; to prevent them?

The Best Memory Leak Definition

I&#39;m looking for a small C library to handle utf8 strings.

Specifically, splitting based on unicode delimiters for use with stemming algorithms.

Related posts have suggested:

ICU http://www.icu-project.org/ (I found it too bulky for my purposes on embedded devices)

UTF8-CPP: http://utfcpp.sourceforge.net/ (Excellent, but C++ not C)

Has anyone found any platform independent, small codebase libraries for handling unicode strings (doesn&#39;t need to do naturalisation).

I am asking this question from an educational/hacking point of view, (I wouldn&#39;t really want to code like this).

Is it possible to implement a while loop only using **C** preprocessor directives. I understand that macros cannot be expanded recursively, so how would this be accomplished?

I want to initialize a struct element, split in declaration and initialization. This is what I have:

    typedef struct MY_TYPE {
      bool flag;
      short int value;
      double stuff;
    } MY_TYPE;

    void function(void) {
      MY_TYPE a;
      ...
      a = { true, 15, 0.123 }
    }

Is this the way to declare and initialize a local variable of `MY_TYPE` in accordance with C programming language standards (C89, C90, C99, C11, etc.)? Or is there anything better or at least working?

**Update** I ended up having a static initialization element where I set every subelement according to my needs.

What&#39;s a better way to start a thread, `_beginthread`, `_beginthreadx` or `CreateThread`?

I&#39;m trying to determine what are the advantages/disadvantages of `_beginthread`, `_beginthreadex` and `CreateThread`.  All of these functions return a thread handle to a newly created thread, I already know that CreateThread provides a little extra information when an error occurs (it can be checked by calling `GetLastError`)... but what are some things I should consider when I&#39;m using these functions?

I&#39;m working with a windows application, so cross-platform compatibility is already out of the question.

I have gone through the msdn documentation and I just can&#39;t understand, for example, why anybody would decide to use _beginthread instead of CreateThread or vice versa.

Cheers!

Update:
OK, thanks for all the info, I&#39;ve also read in a couple of places that I can&#39;t call `WaitForSingleObject()` if I used `_beginthread()`, but if I call `_endthread()` in the thread shouldn&#39;t that work? What&#39;s the deal there?

Windows threading: _beginthread vs _beginthreadex vs CreateThread C++

What is the standard encoding of C++ source code? Does the C++ standard even say something about this? Can I write C++ source in Unicode?

For example, can I use non-ASCII characters such as Chinese characters in comments? If so, is full Unicode allowed or just a subset of Unicode? (e.g., that 16-bit first page or whatever it&#39;s called.)

Furthermore, can I use Unicode for strings? For example:

    Wstring str=L&quot;Strange chars: &#226;&#194; Čšđ ě €€&quot;;


Using Unicode in C++ source code

Any thoughts on why this isn&#39;t working?  I really thought &#39;ignore&#39; would do the right thing.

Python UnicodeDecodeError - Am I misunderstanding encode?

Assuming I have fonts installed which have the appropriate glyphs in them, is there a command shell for Windows XP that will display Unicode characters? At a minimum, two things that should display Unicode correctly:

  * Directory listings. I don&#39;t care what I have to type (dir, ls, get-childitem, etc.), so long as files with Unicode characters in their names appear with the right glyphs, not the unprintable character box.
  * Text file content listings. Again, doesn&#39;t matter to me if it&#39;s &#39;less&#39;, &#39;more&#39;, &#39;cat&#39;, &#39;dog&#39;, etc., so long as the characters are printed. I recognize that this is more complicated because of character encoding of the file, so if I have to specify that on the command line that&#39;s fine with me.

Here&#39;s what I&#39;ve tried so far:

  * cmd.exe
  * Windows PowerShell; including the multilingual version.
  * Cygwin bash

No luck. I even tried installing [custom fonts for cmd/PowerShell][1]. PowerShell and cmd.exe seem to be Unicode-aware in the sense that I can copy/paste the non-printable box out of there and it will paste into other apps with the correct characters. Cygwin (?) seems to convert to the ? character and that comes through in the copy/paste.

Any ideas?

Is there a Windows command shell that will display Unicode characters?

We have a project in Team Foundation Server (TFS) that has a non-English character (š) in it. When trying to script a few build-related things we&#39;ve stumbled upon a problem - we can&#39;t pass the **š** letter to the command-line tools. The command prompt or what not else messes it up, and the **tf.exe** utility can&#39;t find the specified project.

I&#39;ve tried different formats for the .bat file (ANSI, UTF-8 with and without [BOM][1]) as well as scripting it in JavaScript (which is Unicode inherently) - but no luck. How do I execute a program and pass it a **Unicode** command line?

How to use unicode characters in Windows command line?

I am not able to understand the differences between `std::string` and `std::wstring`. I know `wstring` supports wide characters such as Unicode characters. I have got the following questions:

 1. When should I use `std::wstring` over `std::string`?
 2. Can `std::string` hold the entire ASCII character set, including the special characters?
 3. Is `std::wstring` supported by all popular C++ compilers?
 4. What is exactly a &quot;*wide character*&quot;?

std::wstring VS std::string

How do I properly set the default character encoding used by the JVM (1.5.x) programmatically?

I have read that `-Dfile.encoding=whatever` used to be the way to go for older JVMs. I don&#39;t have that luxury for reasons I wont get into.

I have tried:

    System.setProperty(&quot;file.encoding&quot;, &quot;UTF-8&quot;);

And the property gets set, but it doesn&#39;t seem to cause the final `getBytes` call below to use UTF8:

    System.setProperty(&quot;file.encoding&quot;, &quot;UTF-8&quot;);

    byte inbytes[] = new byte[1024];
        
    FileInputStream fis = new FileInputStream(&quot;response.txt&quot;);
    fis.read(inbytes);
    FileOutputStream fos = new FileOutputStream(&quot;response-2.txt&quot;);
    String in = new String(inbytes, &quot;UTF8&quot;);
    fos.write(in.getBytes());

Setting the default Java character encoding

I want to write out a text file.

Instead of the default UTF-8, I want to write it encoded as ISO-8859-1 which is code page 28591. I have no idea how to do this...

I&#39;m writing out my file with the following very simple code:

    using (StreamWriter sw = File.CreateText(myfilename))
    {
        sw.WriteLine(&quot;my text...&quot;);
        sw.Close();
    }



How do I write out a text file in C# with a code page other than UTF-8?

I&#39;m currently working on a Java project that is emitting the following warning when I compile:

    /src/com/myco/apps/AppDBCore.java:439: warning: unmappable character for encoding UTF8
        [javac] 		String copyright = &quot;� 2003-2008 My Company. All rights reserved.&quot;;

I&#39;m not sure how SO will render the character before the date, but it should be a copyright symbol, and is displayed in the warning as a question mark in a diamond.

It&#39;s worth noting that the character appears in the output artifact correctly, but the warnings are a nuisance and the file containing this class may one day be touched by a text editor that saves the encoding incorrectly...

How can I inject this character into the &quot;copyright&quot; string so that the compiler is happy, and the symbol is preserved in the file without potential re-encoding issues?

&quot;unmappable character for encoding&quot; warning in Java

I&#39;m having some brain failure in understanding reading and writing text to a file (Python 2.4).

    # The string, which has an a-acute in it.
    ss = u&#39;Capit\xe1n&#39;
    ss8 = ss.encode(&#39;utf8&#39;)
    repr(ss), repr(ss8)

&gt; (&quot;u&#39;Capit\\xe1n&#39;&quot;, &quot;&#39;Capit\\xc3\\xa1n&#39;&quot;)

    print ss, ss8
    print &gt;&gt; open(&#39;f1&#39;,&#39;w&#39;), ss8

    &gt;&gt;&gt; file(&#39;f1&#39;).read()
    &#39;Capit\xc3\xa1n\n&#39;

So I type in `Capit\xc3\xa1n` into my favorite editor, in file f2.

Then:

    &gt;&gt;&gt; open(&#39;f1&#39;).read()
    &#39;Capit\xc3\xa1n\n&#39;
    &gt;&gt;&gt; open(&#39;f2&#39;).read()
    &#39;Capit\\xc3\\xa1n\n&#39;
    &gt;&gt;&gt; open(&#39;f1&#39;).read().decode(&#39;utf8&#39;)
    u&#39;Capit\xe1n\n&#39;
    &gt;&gt;&gt; open(&#39;f2&#39;).read().decode(&#39;utf8&#39;)
    u&#39;Capit\\xc3\\xa1n\n&#39;

What am I not understanding here? Clearly there is some vital bit of magic (or good sense) that I&#39;m missing. What does one type into text files to get proper conversions?

What I&#39;m truly failing to grok here, is what the point of the UTF-8 representation is, if you can&#39;t actually get Python to recognize it, when it comes from outside. Maybe I should just JSON dump the string, and use that instead, since that has an asciiable representation! More to the point, is there an ASCII representation of this Unicode object that Python will recognize and decode, when coming in from a file?  If so, how do I get it?

    &gt;&gt;&gt; print simplejson.dumps(ss)
    &#39;&quot;Capit\u00e1n&quot;&#39;
    &gt;&gt;&gt; print &gt;&gt; file(&#39;f3&#39;,&#39;w&#39;), simplejson.dumps(ss)
    &gt;&gt;&gt; simplejson.load(open(&#39;f3&#39;))
    u&#39;Capit\xe1n&#39;


Unicode (UTF-8) reading and writing to files in Python

What are the differences between UTF-8, UTF-16, and UTF-32?

I understand that they will all store Unicode, and that each uses a different number of bytes to represent a character. Is there an advantage to choosing one over the other?
