------------------ Additional Follow-up Comments ----------------------------
The attached patch adds (I think complete) Unicode support for Xsharp and Xft. 
This fixes the Umlaut and sz problem when Xft support is enabled.

The patch converts strings into wide char strings (32 bit characters) using 
mbsrtowcs, which seems to be part of the C89 and UNIX98 / Single UNIX 
Specifications and thus should be avaible on all Unices. A quick google says it 
is also avaible on Mac OS X (being a BSD) and Windows / Visual Studio 6, so 
this should be pretty portable.

I think we could fix the Umlaut problem as well using the iconv call (also part 
of the libc like mbsrtowcs). We can't use mbsrtowcs here because standard Xlib 
XDrawFont is only avaible in an 8bit and a 16bit version. But it would be a bit 
more complicated as the non-Xft methods in Xsharp are more complicated.

Summary:  German umlauts and german sz are not displayed

Original Submission:  german umlauts and german sz are not displayed in pnet 
0.6.6. 

In MS .NET the test exe (TestGermanUmlaut.exe) produces a correct display of 
all umlauts and the german sz, see Screenshot_CorrectDisplayGermanUmlaut.jpg.
In pnet the same exe only displays the texts without all umlauts, see 
Screenshot_WrongDisplayGermanUmlaut.jpg.

When compiling the source file (TestGermanUmlaut.cs) with pnet's cscc, it seams 
like the compiler removes the umlauts, because there are the following warnings 
: invalid UTF-8 sequence,..., see Compile_TestGermanUmlaut.txt.
This it not true, because when setting the locale address@hidden the german 
umlauts are correctly displayed in pnet.

I think it is a bug if for displaying unicode text the appropriate locale must 
be set.

Compiling "UmlautTest.cs" with the following command:
"cscc -winforms -g -o UmlautTest.exe UmlautTest.cs"
All umlauts are displayed correct.

If the file is compiled with the following csc syntax:
"cscc /out:UmlautTest.exe /debug /r:System.Drawing.dll,System.Windows.Forms.dll 
UmlautTest.cs",
other characters are displayed for the umlauts.

The test file is in utf-8 encoding, local encoding is also
utf-8.

It looks to me like this is hitting a TODO in XsharpSupport.c in the 
TryCreateFont function.
