CharData should probably contain strings representing graphemes. #3

Currently this holds Runes, which is limiting, needs to hold graphemes.

CharData currently stores a rune, which will not work for grapheme clusters, which are represented as strings in .NET. I do not want to keep a discriminated union there, because it will be costly, so what I think i want to do is to abuse the high-bits of the rune to make those an index into a grapheme cluster table.

This should give me some 2048 values that could be used to encode the grapheme cluster.
