in reply to Unicode vulgar fraction composition

I think you'll have to DIY. The module is implementing unicode.org algorithm, see references in docs. In the context of Unicode, character composition is the process of replacing the code points of a base letter followed by one or more combining characters into a single precomposed character; and character decomposition is the opposite process.

    Right, which is why, on the surface, it's curious that both NFKD and NFKC return decomposed forms. Some illumination is provided in the documentation: NFKD performs "compatibility decomposition," while NFKC performs "compatibility decomposition followed by canonical composition." So apparently what I want is "compatibility composition," which it seems nothing in that module performs. Thus my question amounts to: does anything else in Perl do compatibility composition?

    And I think you are just restating the obvious from the OP.
