Can't do this in swift:

The flat glyph is in theUnicode block Miscellaneous symbols (Unicode U+ 266D). Looks like that's outside the allowable characters for an identifier per Swift 5.1 docs.

Thanks for looking that up @stschoen :)

I'm not sure why they chose to exclude some blocks of unicode characters. If you look at the list of allowable characters, there are holes in the list. Some make sense like combining diacritical marks and spacing characters, but I see no reason for the others. Makes sense to someone I guess.
