[Lazarus] FileExistsUTF8() difference between Unix/Windows

[Torsten Bonde Christiansen]

Is it a bug that FileExistsUTF8(...) reports true/false differently for 
folders in Unix and Windows.

On a unix platform (Mac/Linux tested) FileExistsUTF8() will return true 
to both folders and files

On windows platform FileExistsUTF8 will return true on files, but false 
on folders.

Best regards
Torsten.
