    Can anyone remind me why Variation sequences aren't the appropriate response to the IPA problem? It seems to me that 'a' + VS1 should be defined as the two-story IPA a, and 'g' + VS1 should be defined as the single story IPA g. It would restrict the set of glyphs that should be used to represent the character, but not create a duplicate encoding - exactly what the variation selectors were encoded for, right?
