Some binaries or some command output (unexpected) can contain control sequence which can cause a terminal to interpret it as changing character set. That's why the prompt becomes unreadable and keystrokes abnormal (lines).

To fix this, there are few possible solutions:

Code:

$ echo -e '\017'

Code:

$ reset

(NOT REBOOT)
or

Code:

$ stty sane

Code:

[root@server]$ cat /etc/localtime
'5´à'õ
`(äû`)Ôì`*ÄÝ`+´Î`,¤¿`-$ à-°`.

[root@server]$

After echo -e '\017' the terminal prompt is fixed.
