Why is there broken Cyrillic in the VBA MS Project 2010 editor?

Question

Character encoding

With unfortunate surprise, I found that in the 21st century, MS Project 2010 cannot enter Cyrillic characters in the VBA editor. All sorts of "?aoa?ao?iaiii" are displayed instead of Cyrillic letters. What is typical - when copying through the clipboard - there is no problem. The font in the VBA options is Cyrillic.
