- A new test walks every code point from U+0000 to U+10FFFF, surrogates
left out, and compares the start and part checks with Unicode Standard
Annex #31's general-category definition of ID_Start and ID_Continue,
written out in the test. The test also checks the set sizes against the
totals in Unicode 16.0's DerivedCoreProperties (141,269 and 144,541).
- The Other_ID_Continue test covers every code point of the property,
U+136A to U+1370 and the zero width non-joiner and joiner included.
- The zero width non-joiner and joiner are part of the Other_ID_Continue
list in chars.rs instead of a separate case.
