We may be able to pull the conversion WideChars => UTF8 =>
a PG encoding into an function.
BTW both PGLC_localeconv() and cache_locale_time() save the current
LC_CTYPE first and restore them just before returning the functions.
I'm suspicious if it's OK when errors occur in middle of the functions.
