If there is a method

bool DoStuff() {
    try {
        // doing stuff...
        return true;
    }
    catch (Exception ex) {
        return false;
    }
}

should it rather be called IsStuffDone()?

Both names could be misinterpreted by the user: If the name is DoStuff() why does it return a boolean? If the name is IsStuffDone() it is not clear whether the method performs a task or only checks its result.

Is there a convention for this case? Or an alternative approach, as this one is considered flawed? For example in languages that have output parameters, like C#, a boolean status variable could be passed to the method as one and the method's return type would be void.
