Subject: Detect non-ascii substrings in a file

I have files encoded in Shift_JIS, that mainly contains JSP source
code (ascii), but sometimes also contains strings that are non-ascii
(japanese words).

So, I would like to know if there is a way with ruby to :
- detect files containing something else than ascii,
- extract the non-ascii strings thare were found.

Thank you !
