fichier

En même temps, si tu mangeais pas tout le fichier...

You write a script which expects a 'file' at some place, but it will break in french locale because 'file' will be replaced with something like 'fichier'.

You have to check that /[[:alpha:]]+/ was 'file' not 'fichier' or 'ファイル', just the same as you would have to check the output of your XML parser that the <file> tag was not <fichier> or <ファイル>, just the same as you would have to check that a binary field was 0x0003 or whatever the flag value was.

The fact that your program expect a field name to be 'file' is unrelated, but is something the user could learn by 1) reading your man page, 2) reading your text output and copying it (if appropriate), or 3) reading your error messages that you should be generating when you see 'fichier="foo.txt"' when you were expecting 'file="foo.txt"'.
