Is it? Isn't the eighth note simply a unique graphic used in the DOS
font to display a single glyph for 0x0D where appropriate?
In other words, 0x0D is not semantically equivalent to EIGHTH NOTE
character, but rather is always CARRIAGE RETURN control character.
The eighth note glyph is just a "control picture", isn't it?
If somebody was converting a file from a DOS code page into Unicode,
would it ever be appropriate to map 0x0D to U+266A [♪] ?
