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. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
