That's interesting. So, given that "Mc" is rendered differently and
collated differently from the sequence of two characters "M" and "c", how
should this be handled?

Is it in fact an issue of script/language, in the same way that Spanish 
collates the character combinations "ll" and "ch" differently?

Presumably then if the sequence "Mc" is encountered in text with language
en-UK (or some other code?) it should be collated differently and rendered
using a superscript c or other method.

Surely there must be some existing standard for this?
