SUMMARY
“Mathematical Alphanumeric Symbols” (range 1D400—1D7FF) have their name shown as NON-BMP-CHARACTER-[hexadecimal code point] and their block shown as Basic Latin even though they don’t appear in it, or in any other block accessible in the application. At least some of these characters exist since Unicode 3.1 (2001).

ex:
Character: 𝘓 U+1D613
Name: NON-BMP-CHARACTER-1D613
General Character Properties
Block: Basic Latin
Unicode category: Letter, Uppercase

2. Press Enter

OBSERVED RESULT
The wrong, generic name and the incorrect block are shown.
The character isn’t findable in any block.
