Localize numbers

If desired, the values (that is, the numbers) can be localized.

https://doc.qt.io/qt-6/qstring.html

The '%' can be followed by an 'L', in which case the sequence is replaced with a localized representation of a. The conversion uses the default locale, set by QLocale::setDefault(). If no default locale was specified, the system locale is used. The 'L' flag is ignored if base is not 10.
