is_combining_mark

fn def is_combining_mark(cp: Int) -> Bool

Whether the codepoint is a non-spacing mark (UAX #9’s NSM).

Exact for every codepoint, read from the generated table rather than a hand-kept list of ranges: a mark that reordering separates from its base renders on the wrong letter, and the scripts that would show it are not ones this package can enumerate with any confidence.

Args:

• cp (Int): The codepoint to test.

Returns:

Bool: True if the codepoint is a non-spacing mark.
