Locales, while fine for things like the language of the error messages
or the format to use to display the time, are *not* a good solution
for things like file names and file contents.
Even on a single Unix machine (without networking), there are
*several* users. Using the locale to find out the charset used for a
file name won't work if these users use different locales.
Same thing for file contents. The charset used must be marked in the
file (XML...) or in the metadata, somehow. Otherwise, there is no way
to exchange files or even to change the locale (if I switch from
Latin1 to UTF-8, what do my files become?)
