In the family name, for FC, yep, that's okay.
I have no idea how it deals with high-ascii stuff in this context, though, hence my concerns...
Given what's involved (which is, well, printing letters on screen, after all
), I'm fairly sure FC itself deals perfectly sanely with it, I'm more concerned with how that translates on the Kindle, and in particular how I'm updating the config shards in the KUAL extension...
