Judge whether it is a Chinese character based on the Unicode code

1. Use the istextunicode function to determine whether the current string is Unicode-encoded.

Bool B = istextunicode (cstmp, cstmp. getlength (), null );

2. determine whether it is a Chinese character based on the Unicode code

Cstring szwords (_ T ("test font "));
Cstring sztmp;
For (; icur <szwords. getlength (); ++ icur)
{
Sztmp = szwords. mid (icur, 1 );

// Calculate the Unicode code of the character
Uses_conversion;
Char * str1 = w2a (sztmp );
_ Bstr_t STR = str1;
Wchar *
Str2 = STR;
Int ichar = * str2;

// Chinese, Japanese, and Korean, hieroglyphics (CJK) from 0x3000 to 0x9fff (UNICODE)
If (ichar> = 0x3000 & ichar <= 0x9fff ))
{
// Chinese, Japanese, and Korean hieroglyphics
}
}
