[Bug 16228] Font matching algorithm should explain cluster-based matching

In terms of normalization, the more I look at this I think we probably need to
use only the "Canonical Composition Algorithm", defined within the definition
of Unicode normalization forms.  

Using NFC means that as part of the canonical decomposition ==> canonical
composition, there are many singleton codepoints which will be transformed (CJK
Compatibility codepoints, symbols like Angstrom and Kelvin, etc.) and "lost" as
part of the recomposition.

Using only the composition step allows authors to control precisely the
rendering of characters via the combination of codepoints + font, something the
usage of NFC does not permit.
