*.replace(); does not work on Arduino Uno Wifi Rev. 2

Hello,

it is not possible for me to get proper results for the following code on all of my Arduino Uno Wifi Rev. 2:
```
String currentLine = "%2216%22,%20%2217%22";

void setup()
{
Serial.begin(115200);
Serial.println(currentLine);
currentLine.replace("%22","");
Serial.println(currentLine);
currentLine.replace("%20","");
Serial.println(currentLine);
Serial.println("The result should be 16,17 but it is not.");
}

void loop()
{
}
```

The serial monitor gives me:
```
%2216%22,%20%2217%22
%2216%22,%20%2217%22
%2216%22,%2217%22
```

The result (the last Serial.println(currentLine);) should be 16,17 but it is not.

Is there any workaround for this problem?

Kind regards

Run the provided sketch on an Arduino Uno WiFi Rev. 2 and compare the serial output with the expected 16,17 result. Start at the String.replace entry point and verify behavior for the encoded strings; done means both replacements produce the expected final output without a workaround.
