Answer 1

$row = utf8_encode( $row );
convertUtf8ToHtml( $row );
$ROW_APP_DATA[] = $row;

See function below:


// converts a UTF8-string into HTML entities
    //  - $utf8:        the UTF8-string to convert
    //  - $encodeTags:  booloean. TRUE will convert '<' to '<'
    //  - return:       returns the converted HTML-string
    function convertUtf8ToHtml(&$utf8, $encodeTags = false ) 
    {
        if( !is_string( $utf8 ) || empty( $utf8 ))
         { return false; }
        $result = '';
        for ($i = 0; $i < strlen($utf8); $i++) {
            $char = $utf8[$i];
            $ascii = ord($char);
            if ($ascii < 128) {
                // one-byte character
                $result .= ($encodeTags) ? htmlentities($char) : $char;
            } else if ($ascii < 192) {
                // non-utf8 character || not a start byte
            } else if ($ascii < 224) {
                // two-byte character
                $result .= htmlentities(substr($utf8, $i, 2), ENT_QUOTES, 'UTF-8');
                $i++;
            } else if ($ascii < 240) {
                // three-byte character
                $ascii1 = ord($utf8[$i+1]);
                $ascii2 = ord($utf8[$i+2]);
                $unicode = (15 & $ascii) * 4096 +
                           (63 & $ascii1) * 64 +
                           (63 & $ascii2);
                $result .= '&#$unicode;';
                $i += 2;
            } else if ($ascii < 248) {
                // four-byte character
                $ascii1 = ord($utf8[$i+1]);
                $ascii2 = ord($utf8[$i+2]);
                $ascii3 = ord($utf8[$i+3]);
                $unicode = (15 & $ascii) * 262144 +
                           (63 & $ascii1) * 4096 +
                           (63 & $ascii2) * 64 +
                           (63 & $ascii3);
                $result .= '&#$unicode;';
                $i += 3;
            }
        }

        $utf8 = $result;
        return true;
    }
