Unicode keysyms would not solve all layout problems. There'll always be the CJK languages which require more complex handling (already done in Qt/GTK+). Toolkits' input modules could already handle input conversion to any language (at least uim+m17n (for all european layouts)+any CJK modules) without any support from X (or wayland). I think that all input can be split into "control" (things like hotkeys/keybindings (including text navigation), (maybe) can be passed to separate agent, separate agent (hypothetically) can e.g. map some hotkeys to mouse/multitouch gestures if user don't have/like keyboard), and "text" (any layout things can be handled with toolkits' IM support). It should make things easier for developers and will make some nice side-effects (like working vim-style keybindings in any layout without extra effort for both developers and end-users). IMHO it's better than "unicode keysyms". _______________________________________________ wayland-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/wayland-devel
