OK, I'll try to switch fpGUI's TfpgString type to alias UnicodeString
an see what happens. Obviously this will be done in a separate branch,
not to screw with Trunk.
So where can I find out what has been implemented and what is missing?
Some or other roadmap, like Lazarus has for it's LCL.
http://wiki.lazarus.freepascal.org/Roadmap#Status_of_components_on_each_widgetset
eg:
Does 2.3.x with UnicodeString support the following (off the top of my head).
* TStringList.LoadFromFile() - what happens if file is UTF-8 encoded
like under Linux.
The file is assumed to be in system encoding (which can be UTF-8). Support
for reading of other encodings has not been decided on about yet and is
not part of the initial plan.
* Does it support > 1byte Locale variables for Currency Delimiter,
etc.. Russian locale
requires a >1 byte char.
It can remain a system encoded ansichar for 100% compatibility, or on
selected platforms become a widechar. Conversion to multibyte (utf8) can
in both cases be inferred by the compiler from type information.
* FindFile, FindFirst? Do they handle Unicode filenames? What about
other file IO calls.
Win32 widestring platform for sure. Not really decided on non-Unicode
platforms yet, they may remain in the system encoding. Autoconversion will
in such case happen based on type information.
* Copy, Length, Pos etc...?
Yup.
* What about usage like: SomeString[x] := 'A';
String element based.
* What if we call external API's with string parameters? XLib,
OpenGL, Win32 etc?
Auto-conversion based on type information.
* Does UnicodeString work on all platforms? Linux, Windows for a start?
Yes, but all platforms will get string=unicodestring.
