    If there are real distinct semantics that were "abusively" unified by the canonicalization, the only safe way would be to create a second character that would have another combining class than the existing one, to be used when lexical distinction from the most common use is necessary.

    So the added character for the modified vowel signs would have the same representative glyph, but would have the additional semantic "contraction" (clearly indicated in their name). This does not break the existing encoding of most texts, but allows a specific usage for contractions where the existing canonical equivalences would be inappropriate.
