It seems that the CLDR data has a transliteration for the other era
characters.  I don't know how relevant this to glibc.

I'm pretty sure we need to adjust the collation data for U+32FF.

For the era data itself, we also need to know the multi-character era
name, so knowing the U+32FF codepoint is of little help (in the sense
that we can ship the changes today and have other projects to supply the
actual glyph shape).

Thanks,
