Re: [NTG-context] Greek in luatex

Yes, except that we need a more powerful version (almost like OTPs) if we want to handle transcriptions properly. The vital point is that it should operate on tokens, not on nodes.

Yes, sure. OTP would work fine here, but I thought Mark IV had already something handy.

Possibly because a single one of the glyphs has a different name in GFS Baskerville, or because a previous gsub rule has e.g. replaced F;i; => Fi;

No, simply because GFS Baskerville has no glyphs for Latin characters, so they're dropped by the token reader and can't be transformed afterwards! Arthur
