qt can't use ^ operator on qchar

The ^ operator in C++ is the bitwise XOR operator, which performs a bitwise exclusive OR operation on two operands. However, the ^ operator is not defined for the QChar type in the Qt framework.

The QChar class in Qt represents a single Unicode character. It provides various methods and properties for working with Unicode characters. However, the bitwise XOR operation is not applicable to individual characters, as it is more commonly used for manipulating sets of bits in integers.

If you try to use the ^ operator on QChar objects, you will encounter a compilation error. The compiler will report that the operator is not defined for the QChar type.

To perform bitwise operations on QChar objects, you can convert them to their corresponding integer values using the unicode() method. This method returns the Unicode code point of the character as an int value. Once you have converted the QChar objects to integers, you can perform bitwise operations on them using the regular bitwise operators such as ^, &, |, etc.

Here is an example that demonstrates how to perform a bitwise XOR operation on two QChar objects:

QChar char1 = 'A';
QChar char2 = 'B';

int codePoint1 = char1.unicode();
int codePoint2 = char2.unicode();

int result = codePoint1 ^ codePoint2;
QChar resultChar(result);

// Print the result
qDebug() << resultChar;

In this example, we convert the QChar objects char1 and char2 to their corresponding integer values using the unicode() method. We then perform the bitwise XOR operation on the integer values and store the result in the result variable. Finally, we create a new QChar object using the QChar(int) constructor, passing in the result value. The result is then printed using qDebug().

Please note that the resulting QChar object may not represent a valid Unicode character if the XOR operation produces a code point that is outside the valid Unicode range. Therefore, it's important to handle such cases accordingly.
