   This is a big problem when writing programs for Windows and Linux.   
   Windows is "Case Preserving" (allowing upper and lower case mixed names,   
   but displaying them the way they were created) while Linux/eFS4   
   requires full match on file names. When accessing Linux files from   
   Windows, matches the Windows behavior. I REALLY wish that I could   
   get the Windows behavior as a mount option in Linux, but apparently   
   it is considered an unsurmountable problem that non-European languages   
   / alphabets do not have the simple (mostly 1-1) relationship between   
   upper-case and lower-case, so to do the "right" thing would require   
   adding locale complexity in the file system. ("Is the mapping per-user   
   or systemwide?", "What to do with ligatures?", etc).   
      
   I wonder how Windows deals with that - Do they just limit the   
   case-matching to UTF-8 characters from the European subset?
