As far as I can see, Junicode just substitutes precomposed vulgar 
fractions instead of corresponding 3-character sequences. Naturally,
this method doesn't have side effects like turning arbitrary numbers
into superscripts, but, of course, it allows to support only a limited
number of combinations. For this reason this is not the recommended
way of implementing the 'frac' feature: the preferred one is exactly
what Linux Libertine does.
