MikroIDE doesn't support Unicode.

If you have written comments on another language (for example on Greek), and you had encountered some strange letters once you open the project in mikroE compilers, you can fix this by changing the System locale in the Control Panel:

On Windows 7: Go to Control Panel -> Region and Language -> Change keyboard and other input methods -> go to tab "Administrative" -> click on the button "Change system locale". After you set the preferred language, restart your computer, so the changes can apply, and open the project in mikroE compiler.

On Windows 10: Go to Control Panel\Clock, Language, and Region\Language -> Change date, time or number formats -> go to tab "Administrative" -> click on the button "Change system locale". After you set the preferred language, restart your computer, so the changes can apply, and open the project in mikroE compiler.
