[jira] [Commented] (GUACAMOLE-520) Japanese keyboard layout for RDP incorrect

["Kazuhiko Tanaka (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17074214#comment-17074214 ] 

Kazuhiko Tanaka commented on GUACAMOLE-520:
-------------------------------------------

    In the discussion, I feel that keyboard recognition and key code recognition are mixed.  What I found was a keycode recognition problem, but no keyboard recognition problem.  Input of symbols etc. was done without problems.  

    I confirmed the problem of "Zenkaku_Hankaku" key in addition to "Caps Lock" and "Hiragana".  If enter the "Zenkaku_Hankaku" key in a Japanese browser, "Zenkaku (keyup 243 and keydown 244)" and "Hankaku (keyup 244 and keydown 243)" will be entered alternately (In each case, a keyup occurs first, followed by a keydown).  However, Guacamole does not seem to recognize these keys.  Entering these keys only switches the browser IME and does not affect the connection destination.  

    I confirmed a strange phenomenon.  If the focus is outside the canvas, it may be recognized that a key has been pressed.  Perhaps the keydown event is not recognized on the canvas.

> 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.
