[bug] Unable to view symbols in U-1CC00 BLOCK!

[ChiefMikeK]

[FEATURE REQUEST] Add a settings option to SHOW ALL LEGAL CODE POINTS after Unicode 15.1 Latest option.

Some fonts for example Iosevka have started to include unicode 16.0-beta characters

• https://www.unicode.org/L2/L2021/21235r-terminals-supplement.pdf

Note: Since RFC 3629 (November 2003), the high and low surrogate halves used by UTF-16 (U+D800 through U+DFFF) and code points not encodable by UTF-16 (those after U+10FFFF) are not legal Unicode values, and their UTF-8 encoding must be treated as an invalid byte sequence.

Closing in favor of #181
Please add option to view unassigned blocks [with exception of the illegal UTF-16 surrogates block]
