Thanks for having implemented it!
Just an additional needed fixup: with the current svn, capitalization of
non-ascii letters does not work for two reasons:
- one needs to use locales to get locale-specific capitalization (e.g.
in turkish, capitalization of i is not I but an I with dot above).
- for compatibility reasons, when chr() is given a value between 0 and
0xff, it builds an 8bit char, not a unicode char. The problem is that
uc() then does not work in UTF-8 locales. Using pack("U",...) always
produces a unicode char.
See attached patch.

A good idea. :) Idealy some future version of loadkeys should automaticaly double the keysyms and convert CapsLock to CapsShift and in order to do this no keymap should use CapsShift directly. In console-setup maybe it will be better to use CtrlL_Lock instead of CapsShift_Lock as CtrlL_Lock is supported by console-tools and by all kernels.

And about the led issue, we need to ask the kernel for an interface to be able to configure which lock should drive which led.

More precisely, as described in the bug report, it works only for the underlying 8bit charset, so in unicode it's latin1.

The reason is known - Caps_Lock works only for English letters. I think there was some patch that fixed the problem but I don't know if it is applied in the Debian kernel. I'll have to remember and check this. Anton Zinoviev -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org

Bug#514212: console-setup: on UTF-8 console, caps lock is turned into a shift lock
Package: console-setup
Version: 1.29
Severity: normal
Tags: patch
Hello,
While upgrading from console-data's keymaps to console-setup, my caps
lock became a shift lock, and the caps lock led doesn't work any more.
This is due to these few lines:
# A hack to work around a bug in the kernel/loadkeys
if (! $acm) {
$xkbsym_table{'Caps_Lock'} = 'Shift_Lock';
$xkbsym_table{'ISO_Lock'} = 'Shift_Lock';
}
which happen to be always executed as my system is UTF-8, just like all
future installed Debian systems. Why is this hack needed? We should
rather fix the bug where it belongs instead of introducing others on all
future installed systems... :)
If the reason has been lost in history (the code dates back from at
least 2005) then we should probably apply the patch to fix the common
case, and let the real bug reappear and get fixed the proper way.
Samuel
