Perhaps it would be reasonable to do something like this:
#ifdef USE_WIDE_UPPER_LOWER/* * use wide char code only when max encoding length > one * and we aren't in C locale */if
(pg_database_encoding_max_length()> 1 && !lc_ctype_is_c()){
where lc_ctype_is_c() is the obvious clone of the existing
lc_collate_is_c() routine. We can reasonably assume that mbstowcs
is going to be unable to offer any useful behavior in C locale.
Comments?
