easier to use iconv and conver the string to the file systems character
setup. http://www.php.net/manual/en/function.iconv.php
But to not have to do work arounds, use the same charset as the file
system when you write your scripts, a mixed charsetup usually will cause
issues when forgetting to convert.

No there is no magic in PHP that would it change what you have hardcoded
in the script to something else just for you using a file system which
don't use the same character setup as you wrote the script in.

Depends on which charset is used for the file system, if they use utf-8,
then no issue, of they use big5 or something else, then you have an
issue again.
You will most likely end up with issus with the file paths as other
operating systems uses / instead of \ (which is used as an escape
character).
