[Dev-luatex] letterspacing and (no) ligatures

Hi, here are two bugs: * in pdftex, \letterspacefont does not disable the ligatures, but this is what happens in luatex. * neither \tagcode nor \pdfnoligatures seem to have any effect (for non-letterspaced fonts, that is). Example: \input luaotfload.sty \font\x="Latin Modern Roman:+liga;+tlig" at 12pt \tagcode\x`\f=-1 % no effect \pdfnoligatures\x % ditto \x fi -- \letterspacefont\y\x 100 % killing the ligatures \y fi -- \bye Best regards, -- Robert
