Symbol pickers include the following broad categories:
o Currency symbols
o Diacritic forms for Latin script
o Arrows and block symbols
o Math symbols
o Supplemental symbols
o Script-specific symbols and letters
More background: The goal would be to add names for use by symbols pickers and TTS. For the latter, the presumption is that the client would already use normalization on the text, and many symbols would have pronunciation by context (eg, 1:3 ==> “one to three ratio”), or affect the prosody of the sentence instead of being spoken. So what we are looking at is the “verbatim” name of a character when the above do not apply.
Note that we already support names for emoji characters and sequences, such as: https://www.unicode.org/cldr/charts/35/annotations/romance.html
For emoji we also support search keywords. That wouldn’t be needed, at least at the start, for other characters.
