[Ltru] Non-Latin-1 Description fields in RFC 4645bis

Here are the Description fields in the proposed RFC 4645bis Registry 
that contain non-Latin-1 characters.  This is presented in blocks 
showing the type and value of the subtag, as well as the non-Latin-1 
description, so readers can look up the full context in draft-4645bis-02 
(or -03, when it's ready).

There are two blocks of listings here.  The first is in hex NCRs, as 
they will appear in RFC 4645bis.  This is shown here for the benefit of 
WG members who cannot see non-Latin-1 characters in their e-mail or on 
the Web-based mailing list archive.  The second block is in UTF-8.

Not all of these Description fields are the sole Description field for 
their respective subtag.  For example, the script subtag 'Ethi' also has 
the description "Ethiopic", so technically it doesn't matter for this 
discussion whether the string "Geʻez" is "Latin-script" or not; the 
subtag already has a "Latin-script" description as required.  However, 
all of the non-Latin-1 Description fields are shown here, to help us 
make a well-informed decision.

RFC 4646bis says, "At least one of the 'Description' fields MUST be 
written or transcribed into the Latin script."  It does not say every 
character in that field must have the word LATIN in its Unicode name, 
must have the "Latn" script property in Unicode, must be present in 
Latin-1, Windows-1252, MES-1, etc.  As Frank points out, we don't have 
an operational definition of "Latin script" to guide us here.

All of the characters in these Description fields do have either the 
"Latn" or "Zyyy" (Common) script property in Unicode, and all belong to 
one of the following Unicode blocks:

* Basic Latin
* Latin-1 Supplement
* Latin Extended-A
* Spacing Modifier Letters
* Latin Extended Additional
* General Punctuation
