Problem in uploading file containing Japanese name in Mozilla Firefox and Mozilla 1.7.x

Hi All,



I've a http file upload program which is not working in a situation
where -

a)       The browser is Mozilla Firefox or Mozilla 1.7.x

b)       The file name is in Japanese

c)       The OS on which the browser running is Windows XP and the
locale is English



The same upload program works fine in the following situations -

a)       The browser is Mozilla Firefox or Mozilla 1.7.x, the file name
is in Japanese, the OS on which the browser running is Windows XP and
the locale is Japanese

b)      For IE 6.0 and above and Netscape 7.1 where the file name is in
Japanese, the OS on which the browser running is Windows XP and the
locale is Japanese or English



Any clue on why is this happening ? Is it a bug in Mozilla Firefox and
Mozilla 1.7.x ?



Regards,

Sourav
