QSettings Unable to read the quoted configuration file

When QSettings reads the key value with English "", the "" will be dereferenced by QSettings by default.

For example, in the configuration file:
key="12345678"
Expect the key value read by QSettings to be: "12345678"
The actual value read is: 12345678

Solution 1: You can use the escape character to prevent the quotation marks from being dereferenced;
Solution 2: The WriteFunc function is provided in Qt's QSetting, so that the quotation marks are not dereferenced by registering the self-defined format reading method;

It is expected that Qt can provide corresponding solutions, and users do not need to implement this solution by themselves;
