搜索汉字返回拼音首字母

工具:vs2005

环境:unicode

 DBCS ；double-byte character set，双字节字符集，用于对 Chinese, Japanese and Korean语言支持

IsDBCSLeadByte( BYTE )； 如果该字节是DBCS字符的第一个字节，则返回非0值

由于原来的搜索匹配占的CPU过高，所以上网查了下资料，换了个简单的搜索，少部分汉字可能无返回.记录如下:

bool In(wchar_t start, wchar_t end, wchar_t code) { if(code >= start&&code<=end) { return true; } return false; }

wchar_t convert(wchar_t n)//返回首字母的函数 { if (In(0xB0A1,0xB0C4,n)) return _T('a'); if (In(0XB0C5,0XB2C0,n)) return _T('b'); if (In(0xB2C1,0xB4ED,n)) return _T('c'); if (In(0xB4EE,0xB6E9,n)) return _T('d'); if (In(0xB6EA,0xB7A1,n)) return _T('e'); if (In(0xB7A2,0xB8c0,n)) return _T('f'); if (In(0xB8C1,0xB9FD,n)) return _T('g'); if (In(0xB9FE,0xBBF6,n)) return _T('h'); if (In(0xBBF7,0xBFA5,n)) return _T('j'); if (In(0xBFA6,0xC0AB,n)) return _T('k'); if (In(0xC0AC,0xC2E7,n)) return _T('l'); if (In(0xC2E8,0xC4C2,n)) return _T('m'); if (In(0xC4C3,0xC5B5,n)) return _T('n'); if (In(0xC5B6,0xC5BD,n)) return _T('o'); if (In(0xC5BE,0xC6D9,n)) return _T('p'); if (In(0xC6DA,0xC8BA,n)) return _T('q'); if (In(0xC8BB,0xC8F5,n)) return _T('r'); if (In(0xC8F6,0xCBF0,n)) return _T('s'); if (In(0xCBFA,0xCDD9,n)) return _T('t'); if (In(0xCDDA,0xCEF3,n)) return _T('w'); if (In(0xCEF4,0xD188,n)) return _T('x'); if (In(0xD1B9,0xD4D0,n)) return _T('y'); if (In(0xD4D1,0xD7F9,n)) return _T('z'); return n; }
