why some characters are not recognized?

[Eidus]

Hi,
I have a problem recognizing the letters of a regional language.
QTextCodec :: codecForName ("UTF-8") - does not help.
Although everything is fine in the database - Application Output does not recognize the characters I need - Ą-Ę-Ė-Į-Ū-Ų-Č and others.
I write:
QTextCodec::codecForName("UTF-8");
QString test = QString::fromUtf8("\u0104\u0118\u0116\u012e\u016a\u0172\u017d\u0160\u010c");
qDebug() << "should be: Ą-Ę-Ė-Į-Ū-Ų-Ž-Š-Č, actually shown: " <<test;
return 0;

In Application Output I have:
Starting C:....build-Pope-Desktop_Qt_5_9_1_MinGW_32bit-Debug\debug\try.exe...
should be: A-E-E-I-U-U-Ž-Š-C, actually shown: "AEEIUUŽŠC"
Only 2 characters are displayed correctly.
What is the solution to this problem?

Hi, this is an almost 10 year old bug/feature in Qt Creator
As you say, it's only a problem in Application Output, for example if you do a QLabel->setText() on the string it will display correctly.
Anyway the recommended workaround is to go to Tools/Options/Environment in Qt Creator's menu and change the "Text codec for tools" from "System" to something else...

Thanks for the reply. Although I don't believe in miracles, I can't find "Text codec for tools" anywhere in QT Creator Settings. There is no in "Options-Environment-Interface", no in " ...- System", or anywhere else.

Hi, it should be there:

Perhaps you need to upgrade your Qt Creator, for this feature to exist you need version 4.15 of Qt Creator (or later).

QT Creator in my computer - version 4.3.1
Very strange situation ...

[hskoglund]

That explains it, your version of Qt Creator is from summer of 2017 but the version required is from May last year.

thank you very much

However, this advice does not help. QT Creator has been updated, Text codec for tools is set to UTF-8, but the required characters are not displayed.

Hi, I just tried on Ubuntu 20.04 using Qt 5.15.2 with gcc 9.4 with the Text codec set to UTF-8 in Qt Creator (like in my screenshot above):

Maybe you also need to upgrade your version of Qt...

I installed QT on 3 computers - version QT 6.2.3, QT Creator - version 7.0.0. On one computer, everything works fine - and you don't even need to set UTF-8 there - even if you set the text codec for tools - LatinArabic - still shows the required characters. On the other two computers, including the one that previously failed to see the required characters, nothing can be done - the Ą-Č-Ę characters did not and do not show. Apparently the problem is somewhere else ... Thank you for paying attention to this issue
