in reply to sed character codes

If you wish to search/replace for a UTF-8 sequence, you'll need a string in UTF-8 format. Encode is the module to use to convert the string to UTF-8. Then, you can search for the bytes using /\xC0\xBF/.

Of course, if the string was read in as ASCII or another single-byte encoding, it should already be in UTF-8, so you should be able to use /\xC0\xBF/ already.

At least, that's how I understand things. I don't have much experience in this area.

    thanks! that was exactly what I was looking for. I just needed the formatting convention, which appears to be:

    \x[A-Z0-9]{2}\x[A-Z0-9]{2}

    More generally, do you (or does anyone else) happen to know where I could find this information for other character encodings?? joe
