One original principle was ensure different encodings, so if the practise in music engraving is to keep them different, they might be encoded differently. > > There are duplicates all over the place, like how the half-sharp symbol is > > encoded at U+E282 as "accidentalQuarterToneSharpStein", at U+E422 as > > "accidentalWyschnegradsky3TwelfthsSharp", at U+ED35 as > > "accidentalQuarterToneSharpArabic", and at U+E444 as "accidentalKomaSharp". > > They are graphically identical, and the first three even all mean the same > > thing, a quarter tone sharp! > > But the tuning system is different, E24 and Pythagorean.

As I pointed out above, the Arabic glyphs were originally taken from Western ones, but have a different musical meaning, also when played using E12, as some do.
