After running cat on some files I get the infamous 'bushes':  . B  '  which I believe are result of encoding being changed.Is there any way to recover the terminal after the encoding has changed?
Encoding changed after running cat
terminal;character encoding;cat
Run reset. From the man page:When invoked as reset, tset sets cooked and echo modes, turns off cbreak and raw modes, turns on newline translation and resets any unset special characters to their default values before doing the terminal initialization described above.  This is useful after a program dies leaving a terminal in an abnormal state.
