Unicode.unicharCompose

Performs a single composition step of the Unicode canonical composition algorithm.

This function includes algorithmic Hangul Jamo composition, but it is not exactly the inverse of g_unichar_decompose(). No composition can have either of @a or @b equal to zero. To be precise, this function composes if and only if there exists a Primary Composite P which is canonically equivalent to the sequence <@a,@b>. See the Unicode Standard for the definition of Primary Composite.

If @a and @b do not compose a new character, @ch is set to zero.

See UAX#15
