   Just to clarify : you're saying that there's no problem with the case of   
   letters in floppies because [my understanding of] FV is wrong.   
      
           But the SFN entry contains bytes, not characters; it is the   
           visual interpretation which is codepage dependent (so #$E5,   
           which I called sigma, could be seen as Otilde or nhacek or ???   
      
   However, you are saying that the presence of (codepage 437; shift-and-3   
   to us) #156 = £ (GBP), which behaves normally in true DOS, is enough to   
   generate a LFN entry in Win32?  If so, that may be a case of having an   
   LFN that does not necessarily need to be counted as such.   
      
   AIUI, the presence of ~ in position 7 of DIR output does not prove that   
   the file has a LFN entry (one can create file ABCDEF~1.EXT in pure DOS);   
   and the absence does not prove that it does not (one can create file A.b   
   in Win32).
