Kazuhiko Tanaka commented on GUACAMOLE-520:
-------------------------------------------
I did additional research by xev command with v1.0.0.
When the "Zenkaku_Hankaku" key was entered for the first time outside the
canvas, "KeyPress" and "keyRelease" of "Zenkaku_Hankaku (0xff2a)" were
repeatedly transmitted. When the "Zenkaku_Hankaku" key was entered for the
second time, "KeyPress" and "keyRelease" of "Shift_L (0xffe1)" were repeatedly
transmitted. Each time press it, the pattern of 0xff2a and the pattern of
0xffe1 appear alternately.
The expected behavior is that it occurs each time the next pattern is
pressed.
A pair of "keyRelease" of "HANKAKU (0xff29)" and "KeyPress" of "ZENKAKU
(0xff28)" is transmitted once.
A pair of "keyRelease" of "ZENKAKU (0xff28)" and "KeyPress" of "HANKAKU
(0xff29)" is transmitted once.

> This is inherently incorrect, as the Japanese keyboard can type far more
> characters than those given here. Even if the missing characters are
> correctly mapped, several of these characters depend on additional,
> Japanese-specific modifier/lock keys which the keymap format does not
> currently define.
