WordPress Localization Impact - salcode/fe-sanitize-title-js GitHub Wiki

As discussed in Issue 1 Add German Umlauts, the results of

echo sanitize_title('Ä ä Ö ö Ü ü ß');

varies based on the current language WordPress is using.

Specifically, when using English (United States) as the Site Language, the result is

a-a-o-o-u-u-s

when using German, the result is

ae-ae-oe-oe-ue-ue-ss

For now at least, the plan is for this plugin to match the behavior of sanitize_title() when the Site Language English (United States) is being used.
