Titles and Schrift in Cyrillic

The problem I have with this theme HomeBuilder.
In the headers are not displayed Cyrillic.
In the directory of my site file custom.js not.
I have files: custom-backround.js
custom-fields.js
custom-header.js
And
As for the main part of the page header to change the Russian language?

 

Hello,

If your theme directory does not contain custom.js file then, Download theme again from your members area and upload it.

After that go to js > custom.js present in your theme directory and remove the code given below

Code:

//cufone
Cufon.replace({
    hover: true
})('#colRight h2')('.reply',{
    hover:true
})('h1')('h2')('h3')('h4')('h5')('h6');
