If a Lettering or Unabridged legend field contains a script not present in the Script(s) field for that side:
- Warn the user that the field should only contain letters/digits/symbols from the coin. (To catch the editors who add description, commentary, translation, transliteration, or placement text in the Lettering field.)
- Add a labeled button for each missing script to allow easy addition of the script to the Script(s) field.
This would require connecting blocks of Unicode to scripts (with a huge number of Unicode symbols like ✿ unconnected to any script).
