wp-config | Type: OtherEnd of Text characters, u0003, aka ‘mystery characters’

Apparently, there can be a mismatch of encoding after a db update by your webhost, and it can result in odd characters appearing in text. This might fix it.

Comment out a couple of standard lines on wp-config.php like so:

//define('DB_CHARSET', 'utf8');
//define('DB_COLLATE', '');

NOTE: the solution above creates more problems than it fixes (if it fixes). Often this character was introduced by copying text from Photoshop or a PDF. The best thing to do is delete the text and retype.

Possible fix (functions.php):

//remove 0003 character
function removeWeirdCharacters($content) {
    $content = preg_replace('/\u0003/', '', $content);
    return $content;
}
