Incorrect display of German Umlaute

So they work just in chrome..?
Link to your site?

Thanks for reply.

No, also in chrome it doesn′t work.

Mmm, but I think it’s a problem on your side, I mean, they’re so in the source: In dieser Zeit haben wir fortw?¤hrend unsere
Does this happen just with customizr?

Tried with “Make”. It′s the same problem.
At the moment can test only IE. Curious: IE 11 and 9 are working, 10 is not working.
Also tried in php 5.5. No way.

Is there something else to change?

So it’s something unrelated to Customizr, and to themes in general…(?) Don’t know how to help, sorry ??

Thanks for your support.
Now I find the mistake: W3 total cache is the reason for.
