I'm using PHP to read in a list of entries and add them to an existing database I've developed over several years; but the new entries have a lot of foreign characters which aren't covered under ASCII or ANSI; hence I'll probably have to switch the database file to Unicode unless there's another option. Are there other options, and if not, how difficult will it be to change the code to read and write in Unicode format? I assume I would just use fopen_utf8 () instead of fopen (), and similarly for writing to the file?
