Utf-8 coding problem

mkolenda

QMessageBox::information(this,"","ł"); is greeting me with Å character.
The same problem exists in table headers and other places. I've solved it there by using deprecated trUtf8() function.

What is wrong? How to deal with that?

Which compiler are you using? Is your source file encoded using UTF-8?

mainwindow.cpp which contains this unlucky string is UTF-8 encoded

If I'm not completely mistaken Qt 4.8 does not assume c-strings to be in UTF-8 by default,
but instead assumes they are in the systems default encoding. Have you tried with:
QString::fromUtf8("mystring");?
