[fpc-pascal] Unicode filenames

[Vincent Snijders]

How does the RTL support using unicode filenames (e.g. file names that 
cannot be represented by the ansi char set)?

For example the FileExists function takes a string which is encoded in 
the system char set. If the system char set is UTF8, like most linuxes 
and Mac OS X, then there is no problem. But on windows using a western 
european charset, I cannot check for existence of a file with cyrilic 
characters, even though I can enter them in the windows explorer and 
create such files.
