Right, but they do have that high bit set and next bit clear so 
you can tell you're in the middle and thus either go backward to 
the count byte to recover this character or go forward to the 
next count byte and drop this char while recovering the stream. 
My brain mixed this up with the rest of it and wrote it poorly 
lol.
