Using Version 0.10.7 of Ethereal (on Windows but that probably doesn't 
matter).
I've captured a TCP Session which happens to contain plain text data with 
the only control characters present being CRLF delimited lines and the 
occasional tab character used in various places in the text.
Ethereal's hex display of these packets clearly shows the tab characters as 
hex value 09.  However in the "Follow TCP Stream" window, these "tab" 
characters are displayed as periods ('.').  Attempts to cut and paste the 
contents of the "Follow TCP Stream" window produce periods instead of tabs 
when pasted.  Attempts to use the "Follow TCP stream"'s "Save AS" button 
with ASCII selected also produce a file containing periods where there 
should be tabs.
