UTF-8 problem in CCS monolingual project

uft8ccs1 Hi everybody! I’ve just run into an obstacle related with UTF-8 encoding in CodeCharge Studio. I have a one language project. The project is in russian. I want to use UTF-8 for my project but the project isn’t internationalized. So, I removed the english language and added a russian. Also, I turned off the using of internationalized features (Project Settings -> Locales and Encodings -> Use internationalized features) because the project isn’t multilingual. As a result, I have a corrupted text (question marks everywhere).

I started to experiment. The problem was in checkbox “Use internationalized features”. After I checked it the encoding fixed! Huh!
