What functions are implemented through?

------ Solution --------------------
E4b880 is the hexadecimal representation of the utft-8 code of "1"
E4ba8c is the hexadecimal representation of the utft-8 code of "two"
U8 indicates the UTF-8 encoded value.

If your string is gbk encoded
$ S = "2 ";
$ S = iconv ('gbk', 'utf-8', $ s );
$ Ch = 'u8'. current (unpack ('H * ', $ s ));

In this way, the u8e4ba8c is obtained.
