why .fromLocal8Bit() is needed

[wagmare]

The first one will use latin1() encoding conversion, the second one will use conversion dependent on your system.

thanks for reply .....
which one is best to follow if my process outputted as
"joystick failed due to ... failure and network closed "

we have to use QByteArray() to get output and put that one in QString should be used ..?
if not using QByteArray() will create a problem?
