UnicodeClass class

A single Unicode named block paired with its inclusive code-point range.

start and end are both inclusive: a rune r belongs to this block when start <= r && r <= end. Ranges never overlap and are stored sorted in the internal registry, which lets findUnicodeClassType stop at the first match.

Example:

const block = UnicodeClass(UnicodeClassType.BasicLatin, start: 0x0000, end: 0x007F);
block.start <= 0x41 && 0x41 <= block.end; // true — 'A' is BasicLatin
