Problems with various keyboard layouts and input methods. It would be hard for me to debug these myself because I'd have to be able to work in the same keymap as I was testing PuTTY in! If anybody can debug these problems it would be greatly appreciated. (Although to get any fixes rolled in, you'll probably need to convince us that it won't break for anyone else's keyboard layout, and that it works across all the Windows versions we support, because we just don't know enough about internationalisation.)

(Some of the items below have been on this list for a very long time, and may in fact have been fixed. Please do let us know if so.)

The svorak (Swedish Dvorak) layout apparently gets a few control combinations wrong: ^W, ^V and ^Z.
On the Danish keyboard, apparently the tilde (~) is acting as a dead key and generating a code in itself; so if you hit ~ and then n, you get a ~ followed by a ñ. (OSD: I can't replicate this on Win2K with a Danish keymap. I get only the ñ.)
There's been a report from a Korean user that Korean multi-byte input doesn't work.
A German user has reported that Caps Lock is more like Shift Lock - it affects a lot of keys other than alphabetics.
I believe there are also Eastern input mechanisms we don't handle sensibly.

There's a fix for dead keys that might make some of this stuff go away.
