Change of Unicode codepoints for music fonts
Here's something that came up in #17739: [MusicXML export] Lyrics do not handle flat and sharp signs but deserves its own discussion here.
I gather Unicode does define a few codepoints for music-related symbols. Well, three at least: flat, natural, and sharp (U+266d,U+266e,U+266f) are defined, and maybe a few others. And FreeSerifMscore will use these instead of the old Mscore1 codepoints. I just want to discuss the implications of this are.
If we are changing the Unicode codepoints for flat and sharp in FreeSerifMscore and the mapping for the text symbols palette, I guess I need to do this for MuseJazz too, yes? And then also update the chord style files that use this font? Not sure if I'd need to keep the old codepoints to avoid breaking older files that have these symbols embedded in text.
And I'd want to know the full list of moved symbols.
