How to use Umlauts from PHP in Javascript

I have a MySQL database that contains German Umlauts (ä, ü, ö, etc). The database fields are all encoded latin1_german1_c (if that matters).

From that database I create a json object that I use with javascript. However each value that contains one of those Umlauts gets set to null right from the get go via:

var json = <?php echo json_encode($results);?>;

then:

>>> console.log(json[0].name)
null

Do I need to encode my document somehow differently? Do I ne开发者_StackOverflow中文版ed to walk through the $results array and encode each value somehow? Or something completely different?

json_encode^Docs expects strings to be utf-8 encoded, not latin-1 encoded - that's why the values get reset to NULL (unset).

You need to re-encode the strings from latin-1 to utf-8 before you use them with json_encode. Look for iconv^Docs or the mb_string library, both can do that:

$utf8 = iconv($in = 'LATIN-1', $out = 'UTF-8', $latin1);
