  The Fl_File_Chooser widget transmits UTF-8 encoded filenames to its user. It is
- recommended to open files that may have non-ASCII names with the fl_fopen() utility 
- function that handles these names in a cross-platform way (whereas the standard 
- fopen() function fails on the MSWindows platform to open files with a non-ASCII name).
