Hi Ben,
That character is probably defined as a unicode 6 math symbol. UTF8proc
is a library that julia uses to do Unicode normalization and it currently
does not support unicode 6 characters. Luckily it seems like Steven
Johnson is on a quest to make every possible unicode symbol available in
Julia so this should be fixed soon.
