@es-w Did you ever figure anything out on this? I'm having the same issue with QML in Qt 5.15.8 where some text is incorrect on the same screen as some correct text. I also explicitly set the font to Roboto prior to displaying any QML. The weird part is, is the same build works on one Red Hat VM, but does not work on a slightly different RH VM.

I wouldn't assume that.

QLatin1String latinStr("Adiós"); qDebug() << latinStr << newStr;

Gives:

"Adi\u00C3\u00B3s"

A workaround that you can try:

QString unicodeStr = "some Uniocode හාහාහා %1"; QString newStr = unicodeStr.arg(QString::fromUtf8(latinStr.data())); qDebug() << newStr;
