Package: xterm Version: 231-1 Severity: important When xterm is switched to UTF-8 mode it is possible to enter UTF-8 characters in bash. However, if an UTF-8 character entered, you can press the backspace two times and it will delete the prompt also.
Steps to reproduce:
1. Start xterm: "xterm -en UTF-8"
2. If you check "VT Fonts" menu (Ctrl+right mouse button) the UTF-8 item is set
(See the attached 01_started_with_-en_UTF-8.png)
3. Set the keymap to US keyboard: "setxkbmap en_US"
4. Enter the some characters: "jkl;'" (See the attached
02_some_en-US_characters_entered.png)
5. Press the backspace 5 times: the characters are deleted.
6. Press the backspace 2 more times: nothing is deleted. (See
the attached 03_the_en-US_characters_deleted.png)
7. Set the keyboard to Hungarian: "setxkbmap hu"
8. Press the same buttons as before, this time the characters: "jkléá" are
shown.
(See the attached 04_some_hu_characters_entered.png)
9. Press the backspace 5 times: the characters are deleted.
10. Press the backspace 2 more times: two extra characters are deleted from the
prompt. (See the attached 05_the_hu_characters_AND_the_promt_deleted.png)
Expected behavior: no more characters can be deleted than was entered.
My locale settings are:
xterm: backspace deletes twice much of characters for each UTF-8 character
