I'm not sure I understand what you mean. An example to illustrate what
I was trying to say: Both French and Castellano can be written using
Latin-1; however, letter `ñ' (`n' with tilde) is not a French letter
(thus, `isalpha ()' would return false with a Latin-1 `fr_FR' locale)
but it _is_ a letter in Castellano (thus, `isalpha ()' would return true
with a Latin-1 `es_ES', although the charset is the same). Conversely,
letter `ê' is a letter in French but not in Castellano, and it is part
of Latin-1.
According to SRFI-14, a Latin-1 implementation should contain _both_ `ñ'
and `ê' in `char-set:letter', regardless of the current language
settings, hence the difficulty we might have building `char-set:letter'.
Does that clarify things?
Thanks,
Ludovic.
