Iirc, there were already some attempts to support it.

It's _very_ old and very outdated. For another thing up to now only guile-1.8 is supported. I've an experimental branch where guile-2.2 is used and LilyPond is more or less working. Look at the difference (all done in a native guile-prompt, no LilyPond): guile> (version) "1.8.8" guile> (define strg "’s He") guile> (map string (string->list strg)) ("�" "\x80" "�" "s" " " "H" "e") guile> As opposed to: scheme@(guile-user)> (version) $4 = "2.2.2.5-96c9" scheme@(guile-user)> (define strg "’s He") scheme@(guile-user)> (map string (string->list strg)) $5 = ("’" "s" " " "H" "e") Cheers, Harm _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
