Arrows / Font issue

Hi Nikola,

We have an issue that seems related with fonts on easy appointments : calendar arrows do not display properly, neither do accents (é) (Firefox 56 and Chrome 61, both on windows and mac).

Here is a screenshot of what we get : http://hpics.li/1cde68b
And a screenshot of the inspector (inspecting right arrow) : http://hpics.li/12324a6

We just checked the demo version, it displays fine, it seems there are no similar issues on the support, could you help us ?

Thanks,
