This got me to look up a UTF-8 to unicode code point command line tool, which it turns out is "uconv -x hex/unicode". The first one looks like mostly mathematical alphanumeric symbols: https://en.wikipedia.org/wiki/Mathematical_Alphanumeric_Symbols https://en.wikipedia.org/wiki/Mathematical_Alphanumeric_Symb... I wonder if anyone has used characters in the unicode private use area. That could have interesting results.
