1965 Returns false if CFLocale has no information about the given locale (in which case none of the by-reference return values are set);
1966 otherwise may set *langCode and/or *regCode to -1 if there is no appropriate legacy value for the locale.
1967 This is a replacement for the CFBundle SPI CFBundleGetLocalizationInfoForLocalization (which was intended to be temporary and transitional);
1968 this function is more up-to-date in its handling of locale strings, and is in CFLocale where this functionality should belong. Compared
1969 to CFBundleGetLocalizationInfoForLocalization, this function does not spcially interpret a NULL localeIdentifier to mean use the single most
1970 preferred localization in the current context (this function returns NO for a NULL localeIdentifier); and in this function
1971 langCode, regCode, and scriptCode are all SInt16* (not SInt32* like the equivalent parameters in CFBundleGetLocalizationInfoForLocalization).
