What is a non-ASCII locale ? Anything that is not LC_ALL=ASCII ?

BTW, it would really help if we had a way to query for locale at

How should one find out which locale we are in ?

I think that the cleanest solution should be to define our own locales 
that can be doctored to satisfy the LIKE optimisation requirements.
We will probably need something like that in the future anyway as AFAIK
SQL 9x requires ability to have locales applicable on field-to-field
not just one per host.
