Why is robots.txt not recognized by Google?

Question

Google

In general, I decided to start optimizing the site, went to google webmaster tools, showed errors in robots.txt. Site on WordPress, the file is generated on the fly. Hovering over the red dot shows "/ufeff". I understand google wants robots.txt to be utf-8 encoded w/o BOM. Website on a dedicated server under CentOS. Creating a robots.txt file with "handles" is an extreme measure, I want everything to work "normally". Who has any ideas?
