Gwt Bootstrap and i18. Special charachters font failures.

[Laurynas Peciukaitis]

Hello,
I am implementing Gwt-Bootstrap3 in my project, which has internationalization in it. I faced one problem : If I'm displaying special characters in Gwt-Bootstrap3 elements i get font failures. You can see picture, there i compared Gwt-Bootstrap button with simple button.  How to avoid this ?
