Answer 1

htmlspecialchars() accepts additional parameters -- the third one being the charset.

Try specifying that third parameter.

Answer 2

You need to add extra parameters to the htmlspecialchars() function. The following should work:

htmlspecialchars($string, ENT_QUOTES, "UTF-8");

Answer 3

您可能希望将一个可选参数传递给htmlspecialchars关于字符集，默认情况下为 ISO-8859-1。

Answer 4

If you require all strings that have associated named entities to be translated, use htmlentities() instead, that function is identical to htmlspecialchars() in all ways, except with htmlentities() , all characters which have HTML character entity equivalents are translated into these entities.

but even htmlentities() does not encode all unicode characters. It encodes what it can [all of latin1], and the others slip through (eg `Љ).

This function consults an ansii table to custom include/omit chars you want/don't.

(note: sure it's not that fast)

/**
 * Unicode-proof htmlentities.
 * Returns 'normal' chars as chars and weirdos as numeric html entites.
 * @param  string $str input string
 * @return string      encoded output
 */
function superentities( $str ){
    // get rid of existing entities else double-escape
    $str = html_entity_decode(stripslashes($str),ENT_QUOTES,'UTF-8');
    $ar = preg_split('/(?<!^)(?!$)/u', $str );  // return array of every multi-byte character
    foreach ($ar as $c){
        $o = ord($c);
        if ( (strlen($c) > 1) || /* multi-byte [unicode] */
            ($o <32 || $o > 126) || /* <- control / latin weirdos -> */
            ($o >33 && $o < 40) ||/* quotes + ambersand */
            ($o >59 && $o < 63) /* html */
        ) {
            // convert to numeric entity
            $c = mb_encode_numericentity($c,array (0x0, 0xffff, 0, 0xffff), 'UTF-8');
        }
        $str2 .= $c;
    }
    return $str2;
}
