Weird text in Message Log

Why do I see error messages with this strange symbols?

E:\Home\Source\Home\Private\Acts\Act_31.cpp(45) : error C2360: ?ய 樠???樨 “blackLinesWidgetClass” ??-?? ??⪨ "case

Looks like an encoding issue. The error seems it could be fixed via c++ - Error C2360: Initialization of 'hdc' is skipped by 'case' label - Stack Overflow

That encoding issue, make sure everything is using unicode, read about it here

Character Encoding

Try seeing this in output log also you may see error by building in VS alone
