In fpGUI we use UTF-8 for everything. We have wrapper file access functions which replaces the RTL ones. The unit is called gfx_utils.pas eg: function fpgFileExists(const FileName: TfpgString): Boolean; begin Result := FileExists(fpgToOSEncoding(FileName)); end; fpgToOSEncoding() is then implemented in platform dependent include files (like FPC also does with many functions). Linux & *BSD X11: --------------------------- // yes we assume UTF-8. Only very old Linux versions don't use UTF-8, but that is very rare now. function fpgToOSEncoding(aString: TfpgString): string; begin Result := aString; end; Windows GDI: ------- function fpgToOSEncoding(aString: TfpgString): string; begin Result := Utf8ToAnsi(aString); end; Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
