[Development] QTranslator - line feed character

[EXT Panajotis Daras]

Hello everyone,

I wanted to ask whether the current behavior in the translation module is correct.
In short, the question is about the line feed character in the translation file:

// hellotr_la.ts file

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.1" language="lv_LV">
<context>
    <name>QPushButton</name>
    <message>
        <source>Hello</source>
        <translation>Hello\nworld!</translation>
    </message>
</context>
</TS>

The customer expects that the translated text will be formatted with respect to the line feed character. However, the translation is displayed as it is written (please see attached image). This behavior comes from the QTranslator<https://doc.qt.io/qt-6.2/qtranslator.html> class, which returns "Hello\\nworld!". Is it a correct behavior? Is there any simple way to change the behavior?

Best regards,
Panajotis Daras
