Please at least add for zh-HK, Chinese (Hong Kong S.A.R., China)
lcidCodes[0xc04] = 950;

so varchar, char will not fail

For completeness, could you gen all LCID mapping from following? It is correct?
var laCultures = CultureInfo.GetCultures(CultureTypes.AllCultures).OrderBy(a => a.TextInfo.LCID)
.Select(a => string.Format("lcidCodes[0x{0:x}] = {1}; //{2}, {3}", a.TextInfo.LCID, a.TextInfo.ANSICodePage, a.TextInfo.CultureName, a.EnglishName)).ToArray();
string lsCulture = string.Join(Environment.NewLine, laCultures);
