WaE: ´nLen´ may be used uninitialized in this function

Looking at the change to this line in e904749eb8e1109f9a884b309fad6de5f78ad623
, I think this line was changed incorrectly. So I won't simply "fix" the
warninig by initialising nLen to some value like zero, but instead reinstate
the use of the nCharCount2 here instead of nLen.
