Non-Webkit Browsers not showing special characters correctly

Question

I use Google Web Fonts in my project, and I got a strange issue. Everything works fine in Chrome, Mobile Safari, Mobile Chrome, and even Android Browser, but in non-webkit browsers (IE11, Latest FF) special characters (in my case "ğ,Ğ") not showing in standard font.

Here's the font imports:

@import url(https://fonts.googleapis.com/css?family=Allura);

@import url(https://fonts.googleapis.com/css?family=Roboto+Slab);

Answer 1

As instructed by Google, you need to request for support to “Latin Extended” in order to get all the Turkish letters right. Instead of

@import url(https://fonts.googleapis.com/css?family=Allura);

use

@import url(https://fonts.googleapis.com/css?family=Allura&subset=latin,latin-ext);

Similarly for other fonts.
