public delegate Bool UnicodeComposeFunc (UnicodeFuncs ufuncs, Codepoint a, Codepoint b, Codepoint ab)
A virtual method for the UnicodeFuncs structure.
This method should compose a sequence of two input Unicode code points by canonical equivalence, returning the composed code point in a Codepoint output parameter (if successful). The method must return an Bool indicating the success of the composition.
