Hi all,

Quick question: I want to use some unicode identifiers, but I get "unsupported char 0xe2", both with using and not using a BOM. The characters in question are the superset/subset-equals operators: ⊇ and ⊆... Perhaps these are just unsupported by DMD (in which case, I'll file a bug)?

Thanks,
Robert

(As an aside, Google's link obfuscation is hella annoying.)

The relevant range is U+2200 to U+22FF (specifically U+2286, U+2287). It's not included.
