[PATCH] Fix Unicode handling in :INVERT readtable and :CASE :COMMON pathnames

[Marius Gerbershagen]

Not all streams may be buffered, think for example user-defined gray 
streams. And even if they implement buffering, it will still be faster 
to have one generic function dispatch instead of maybe 10 or 20 for each 
character. Since symbols are so common data types, I think the small 
optimization is worth it there.
