Url issues with Hebrew

Hi folks

I’m really enjoying this theme, worked with other themes before, but this is different and really good.

I’ve been having issues with creating pages/posts that within their url there’s Hebrew letters,
for example, this link: http://ikbf.co.il/עברית/ ‎
Once clicked moves directly to this url = http://ikbf.co.il/?/
and then it leads to the main page.

What I did to “go around it” so far is to change all the links to English names (in the main menu for instance).

I know that this is not ideal for SEO, but I was ready to go along with it until I’ve had more issues when implementing a calendar, the one that’s on the index page right sidebar.
Since the name of the event is also in Hebrew, it doesn’t work…

Any ideas?

Please note that I’m not a programmer, but I’m trying my best 🙂

**** THANK YOU ****
