Function ucd_util::hangul_full_canonical_decomposition

pub fn hangul_full_canonical_decomposition(
    cp: u32
) -> Option<(u32, u32, Option<u32>)>

Return the full canonical decomposition of the given precomposed Hangul codepoint.

If the decomposition does not have any trailing consonant, then the third part of the tuple returned is None.

If the given codepoint does not correspond to a precomposed Hangul codepoint in the inclusive range AC00..D7A3, then this returns None.

This implements the algorithms described in Unicode 3.12 and Unicode 4.8.
