Remove every occurrence of special characters in QString

How can I remove every occurrence of the special characters ^ and $ in a QString?

I tried:

QString str = "^TEST$^TEST$";
str = str.remove(QRegularExpression("[^$]."));

You could not escape ^

. To avoid this, it is required \

, but also necessary, to be escaped because of the C strings. Also, you want one or more inputs to match +

. This regular expression should work: [\\^$]+

, watch online .

So it should be:

QString str = "^TEST$^TEST$";
str = str.remove(QRegularExpression("[\\^$]+"));


Another possibility, described in the comments below from Joe P :

QString str = "^TEST$^TEST$";
str = str.remove(QRegularExpression("[$^]+"));

because it ^

only has a special meaning at the beginning where you have to avoid it, to get it literally, look online .
