One original principle was ensure different encodings, so if the practise in music engraving is to keep them different, they might be encoded differently.

They are graphically identical, and the first three even all mean the same thing, a quarter tone sharp!

That seems obvious. 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.
