New zh_HK.BIG5HK Locale to Support HKSCS for Hong Kong, China

The new zh_HK.BIG5HK locale is provided to support the Hong Kong Supplementary Character Set (HKSCS). The HKSCS is a supplementary character set of the Big-5 and ISO 10646 coding schemes. HKSCS contains Chinese characters that are needed in Chinese computing in Hong Kong. However, these characters are not contained in either the Big-5 or ISO 10646 standard character sets.
