Please explain Unicode and non-unicode support in lazarus

[Человек_Борща]

Greetings!

Please, explain me, what about unicode support in Lazarus?

It's supported or not in Lazarus/FPC, if yes, where it supported?

I need something like Delphi 2009 Unicode support.
In lazarus 1.2.6, function DeleteFile('some non ANSI chars(russian for example)') will not work propertly.

For the unicode support, I write two versions of one function:

Code: [Select]

{File 32bit CRC}
function GetCRC32OfFileA(const sFile: ansistring): ansistring; overload;
function GetCRC32OfFileW(const sFile: WideString): WideString; overload;
The first is ANSI version, compatible with string and UTF8String types. Russian "AS IS" chars will not work.
The second function, I rhink, will work with unicode chars without problems.

It is supported by AnsiString + UTF8 specific functions. See :
  http://wiki.freepascal.org/LCL_Unicode_Support

Lazarus 2.0 will improve things.

The Windows unit won't really change in newer FPC versions, since that is the interface of Windows operating system, and windows won't suddenly start supporting utf8.

On Windows, Utf8 is for textfiles only, not for APIs.

The only change that still must happen is to switch the default names (e.g. GetCRC32OfFile) from the -A to the -W alias, similar like D2009 did
