Problems with Bushwick on WordPress.com

Hi,

As in title, I am using Bushwick theme in WordPress.com and have some issues. First of all, the font does not work well with some not English characters like “ł”, “ó” or “ż”. Is it possible to change the font or manage this issue somehow?
Second thing is the “You may also like” section which used to appear at the bottom of every post but now it disappeared 🙁 I think it was extremely useful and encouraged readers to read other posts. How can I get this section back?

I am aware that working on WordPress.com limits my options but I’m really not comfortable with any programming so I’d like to avoid moving to ww.wp.xz.cn

Here is a link to my blog: http://heavyrunslight.wordpress.com/

Cheers

Paul
