Hi Deborah,

The Mac Gaelic and Mac Celtic character sets were released in the Irish
localization of System 6.0.7 and 7.0.1 years and years ago. Last time I
looked, however, Apple mappings for these (which I had provided) were not
on the Unicode CD or the Unicode site. Why not? Same goes for the Mac Inuit
character set now being used (and blessed by Apple Canada) 0

Not a single one? Not Simple Text? What's the mechanism for entering
characters? (You need something like PopChar at least and probably a nice
ResEdit interface for designing KCHRs.

Not sure what that means.

Well, I'd be happy to look at it... Is UTF-16 OK for HTML documents, though?

Considering the size of the Apple plant down in Cork, and the enthusiastic
support Apple receives from Ireland.... what could we do about that?

We live and hope. :-) Thanks for answering.
