Greetings, Monks.

Unicode has precomposed fractions, such as VULGAR FRACTION THREE EIGHTHS (U+215C), that Unicode::Normalize's NFKC or NFKD function decomposes into the string "3\N{FRACTION SLASH}8".

But I can't get any function in that module to go the other way, turning the decomposed form back into the vulgar fraction. Clearly the module is aware of the equivalency of these forms. And while it wouldn't be difficult to write my own function to handle these fractions (there are only a dozen or so), rolling my own code to do a translation that already lives inside Unicode::Normalize seems like a wrongheaded approach. Is there a standard mechanism or tool for composing arbitrary fractions into precomposed ones, where such precomposed ones are available?
