After unpacking, preferably a copy of the DLL, you can run strings on it, piping the results through less,
strings WPCONFIG.DLL | less
And see all text in the DLL. Strings is not perfect so you do get some garbage mixed in. There's a lot of strings in this DLL.
Or if you know what you are looking for, use grep,
H:\tmp>strings WPCONFIG.DLL | grep "POINTERS"
NAMEFILTER=*;CLASSLIST=WPPointer;STARTFOLDER=?:\OS2\POINTERS;DEFAULTCRITERIA=YES
