It sounds like your terminal window is dropping into the alternate character set which, by default, is the DEC VT100 line drawing set. It has lots of lines, corners, and weird looking things as well a characters to represent various control characters in place of all lower case characters. Upper case character should be unaffected. Sending a 0xF (CTRL-O) will flip you back to the normal set and it is documented in one of the xterm files, ctlseqs.ms, but I fix it with a hard reset in my term. Assuming it's an xterm, that is found in the CTRL-button2 menu. In gnome-terminal, left-button and "Reset Terminal". Ugly, but better than a reboot. Depending on your console setup, it could even happen in console mode. for this, you want the control character. The question is, what is sending the control character (0xE or CTRL-N) to flip the character set? It usually happens to me when in inadvertently send a binary file to my terminal. R.
