You can use the following code for going back and forward.
if (!function_exists('codepoint_encode')) {
function codepoint_encode($str) {
return substr(json_encode($str), 1, -1);
}
}
if (!function_exists('codepoint_decode')) {
function codepoint_decode($str) {
return json_decode(sprintf('"%s"', $str));
}
}
echo "\\nUse JSON encoding / decoding\\n";
var_dump(codepoint_encode("我好"));
var_dump(codepoint_decode('\\u6211\\u597d'));
Use JSON encoding / decoding
string(12) "\\u6211\\u597d"
string(6) "我好"
