Comment (by vegansalad):

 I should state, not every dingbat is broken in the Linux TBB. The Up Down
 Arrow works:
 https://www.fileformat.info/info/unicode/char/2195/browsertest.htm

 Also, a regular multiplication sign works
 https://www.fileformat.info/info/unicode/char/00D7/browsertest.htm but a
 "MULTIPLICATION X" does not
 https://www.fileformat.info/info/unicode/char/2715/browsertest.htm

 I'm not sure which whitelisted font allows some of these to work.

 It might be good to find a good font candidate to whitelist in the Linux
 and Windows TBB to allow it to render more unicode characters than the
 current fonts allow. I haven't done any tests on the Mac TBB.
