Indeed, the route I had in mind was:

1) Determine script from character(s).

2) Categorise script as Western/CTL/CJK

3) Locale is then the Western locale, the CTL locale or the CJK locale
as appropriate.

Unless one first categorises the script, one does not know what the
language is.

Now, with more support, one may need the script.  For example, a
Serbian date field should depend on the script (Latin v. Cyrillic) as
well as just the language, and Serbian is not the only language using
competing scripts in the same class.  However, what a date field picks
up from its environment is curious.  If I copy a Thai date field and
paste it into the middle of an English word, I get a date in English!
