QString encoding problem

[sonulohani]

Hi,
I have a code in Qt5 which looks like this:-

QString str("âáéì");

Whenever I am converting it to C++ std::string using toStdString(), Its giving me invalid characters. I have tried all encoding and its not working at all. I have my Qt built with ICU libs. Please help me in this regard.

BTW if i print QString using qDebug() its printing ????

What version of Qt5?

the problem is when you insert it this way the default encoding from the compiler/file is taken. Which is most probably not what you want for special characters.

Use the unicode escaping syntax to ensure the correct character data. e.g. "\uf02a" or whatever.

how do you excactly check for those "invalid" characters?

what do you mean?
A "character" is just data. It just matters if you interpret it as a (Unicode-)character.
Thats why i asked how you exactly check for those "invalid" characters?
