how do u put custom fonts?

I love the enfold theme so far.
However, I faced font type problem for other languages.
I’m trying to put other language fonts but seems not possible.
I been looking everywhere but have not found ‘working’ way to do it yet.

So far I was able to generate .woff file from .ttf file.
I’m trying to change at least menu font that is not in English.

Thank you in advance.
