EUC Japanese + regex

[vermaha]

Is there anyone who has ever done this: find all double byte strings in a document using regular expressions?

I'm going through a large number of web/PHP pages that need to be translated (about 1000) and I need to match all EUC Japanese text (between single, double quotes; between tags + optional spaces that might occur before or after the Japanese pieces).

preg_match(REGEX, $mytext, $matches);

Any help appreciated.
Thanks a lot!
