Comment 58 for bug 85579

Found anther issue when running on the Japanese windows. If the folder name
contains a Japanese char whose double byte code is '837C' (note that '7C' is
'|' which is an illegal char on win32 in the code) then we'll end up hashing the
folder name and we'll get 'Unknown error' msg when opening the folder. So in
this case we should not hash the folder name. But if I enter 'a|b' then we'll
want to hash the name. Question is how does the code tell if a particular '7C'
char comes from a Japanese char or it's from the ASCII '|'?
