I use a text file for my two-letter pairs, and build my font file with FEIDIAN. Problem is, there are a LOT of pairs, and I've accidentally let a few dupes sneak in there. Does anyone know of an easy way to remove the duplicates? Perhaps within OpenOffice Calc (which I have) or a simple Perl script? I need it to be case-sensitive and not mess with whitespaces. Anyone? Please?
