Change your Windows system setting --> Regional and Language Settings --> Language for non-Unicode programs --> set to English

I haven't tried the suggestion above myself

Or please do not use Windows OS :cries: (and why I have to)

If every .ui file in the examples has this problem and consider the fact that those files are supposed to teach Qt. I suggest you do not use that book to learn. It is common sense not to use non-English characters in program source files (and nowadays everyone can write a book...).


For this special file,
Open in binary mode and alter the byte at address 0x6CE to an English character.
