            Bug ID: 94279
           Summary: wl_keyboard and hieroglyphs
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: wayland
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: gramkueo at sharklasers.com

Now the physical keyboard in the core protocol of "wl_keyboard", works on the
principle of key codes from the library "xkbcommon". A virtual keyboard is
implemented as an extension to the protocol: the client come characters in
utf-8. But did you have to separate these 2 entities: physical and virtual
keyboards? In the first case, the keyboard layout is given to the client, in
the latter case - the compositor. What about the hieroglyphs? Compositor needs
a clue, where exactly on the surface entering the symbol to displaying a menu
select the desired character input via pinyin. But in addition to pinyin is
required and directly write characters encoded in some encoding like utf-8. Key
codes there is clearly no help, because even if you switch to "en-ru" layout
weston-terminal eats up the next character, and "ctrl с" where "с" - russian
character, completely blocks the ability of entering text. Weston-editor always
writes to stdout "input language is en," although it is not.

Why initially it was impossible to give layouts to compositor, clients to give
utf-8 characters and modifiers separately? Yes, bind the protocol to a single
encoding may not seem right, but we all understand that in today's world means
utf-8 after the chaos of single-byte encodings? In the result, we get
guaranteed delivery to the client of that character, who wanted to send the
user. As features could as wl_keyboard to send utf-8 characters from the
microphone, hand gestures from a video camera or special devices for people
with disabilities.
