ICU still depends on libc for compatibility with certain historical behavior for single-byte encodings. Make the dependency explicit by holding a locale_t object when required. We should consider a better solution in the future, such as decoding the text to UTF-32 and using u_tolower(). That would be a behavior change and require additional infrastructure though; so for now, just avoid the global LC_CTYPE dependency.
