How to convert Chinese to bytes

How to convert Chinese to bytes, for example, "Guangdong" to byte [] = {[-27,-71,-65,-28,-72,-100]}

To use a ready-made function, you still need to compile a function a little.

Reply to discussion (solution)

Var B = Encoding. UTF8.GetBytes ("Guangdong"); Console. WriteLine (string. Join (",", B ));

229,185,191,228,184,156

Byte is an unsigned integer. if you need a negative number, it will be reduced by 256 for each item.

Seek for direct php code for temporary use, and study it carefully later

$ S = "Guangdong"; $ s = iconv ('gbk', 'utf-8', $ s); $ r = array_map ('ord ', str_split ($ s); print_r ($ r );

Array(    [0] => 229    [1] => 185    [2] => 191    [3] => 228    [4] => 184    [5] => 156)

Or

$ S = "Guangdong"; $ s = iconv ('gbk', 'utf-8', $ s); $ r = unpack ('C * ', $ s ); print_r ($ r );

Array(    [1] => 229    [2] => 185    [3] => 191    [4] => 228    [5] => 184    [6] => 156)

Or

$ S = "Guangdong"; $ s = iconv ('gbk', 'utf-8', $ s); $ r = unpack ('C * ', $ s ); print_r ($ r );

Array(    [1] => -27    [2] => -71    [3] => -65    [4] => -28    [5] => -72    [6] => -100)
