Package: xterm
Version: 396-1
When modifyOtherKeys is set to mode 2 in xterm, pressing the Alt key in
combination with letters on a non-Latin keyboard layout does not produce any
escape sequences or characters. This makes it impossible to bind these key
combinations to specific actions within applications running inside xterm.
Expected behavior: When modifyOtherKeys -specific sequence cannot be
generated, it should send an escape character followed by the corresponding
Unicode character, mirroring the behavior observed when modifyOtherKeys is
disabled (mode 0).
Current behavior: No escape sequence or character is sent when Alt is combined
with letters in non-Latin keyboard layouts if modifyOtherKeys is set to 2.
Steps to reproduce:
*
Configure a non-Latin keyboard layout (e.g., Russian, Greek, etc.).
*
Start xterm with modifyOtherKeys set to 2 (either through a resource file or
command-line option).
*
Run showkey -a, press Alt in combination with various non-Latin letters.
*
Observe that no escape sequences or characters are output.
This issue hinders the usability of xterm with non-Latin keyboard layouts when
custom keybindings relying on Alt key combinations are desired (like in far2l
project in which I contribute code from time to time). A fix would greatly
improve accessibility and allow users to fully leverage their keyboard's
capabilities within xterm.
