Thanks, that workaround works, but with 2.6.4 have another type of problem:
1.Home dir is C:\Users\Željko
2.DirectoryExistsUTF8, any file inside $HOME FileExistsUTF8 and other 
file routines from LazFileUtils works like a charm.
3.IniFiles - TMemIniFile uses UpdateFile, and of course eg. 
C:\Users\Željko\myinifile.ini fails to update because UpdateFile 
inifiles uses ForceDirectories() ...
4.I said ok, let's create it with:
  a) UTF8ToSys(AFileName) - does not work
  b) UTF8ToConsole(AFileName) - does not work
  c) UTF8ToAnsi(AFIleName) - does not work
  d) LConvEncoding.UTF8ToCp1250(AFIleName) WORKS

So, have I missed something about UTF8ToSys() and others in case of 
fpc-2.6.4 ?

NOTE: I'm talking about fpc-2.6.4 ! fpc-3.0.0 works correct in this case
