This isn't really possible with OpenType as the power of GSUB and GPOS =
lookups is rather limited. It's unfortunately not regex-like at =
all=97everything has to be hard coded. It's also far too deep of a =
problem for a font to solve on it's own=97scripts * languages * =

transformations * authors' preferred markup syntax. The table sizes =
would be monstrously large if one could even get past the size limits =
that are part of the GSUB and GPOS format.
