AltGr 在使用 UHID 键盘 + 丹麦语键盘布局时不起作用

Using the UHID keyboard with scrcpy and the Danish keyboard layout does not allow AltGr to be used. # System Specs - Operating system: Arch Linux - Display server protocol: Wayland - Compositor: Sway - Keyboard Layout: Using the Danish keyboard layout as can be seen here: (source of picture here) # Phone specs - Phone: Google pixel 9 pro XL - Operating system: GrapheneOS. - Keyboard: Using the default android keyboard bundled with GrapheneOS, Danish layout. # Description of problem Scrcpy is running through xwayland. Running scrcpy --video-codec=h265 --max-size=1920 --max-fps=60 --no-audio --keyboard=uhid --shortcut-mod lalt -V verbose and pressing+releasing AltGr gives the following output: > VERBOSE: hid keyboard: key down scancode=e6 (230) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 > VERBOSE: hid keyboard: key up scancode=e6 (230) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 However, upon pressing e.g. AltGr+2 to input the character '@' in scrcpy, the character is not input. '2' is simply input. There is an odd thing, however. The ´ -button (located just to the left of the backspace button on my keyboard) does not input anything in scrcpy when pressed on its own. However, if the ´ -button is pressed twice with AltGr held down in scrcpy, the character ´ is input. This character is normally input when pressing the button on its own without AltGr in my operating system. The following output is obtained by Pressing AltGr-->pressing the ´ -button twice -->releasing AltGr in scrcpy: > VERBOSE: hid keyboard: key down scancode=e6 (230) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 > VERBOSE: keys[2e] = true > VERBOSE: hid keyboard: key down scancode=2e (46) mod=00 > VERBOSE: input: UHID input [1] 00 00 2E 00 00 00 00 00 > VERBOSE: keys[2e] = false > VERBOSE: hid keyboard: key up scancode=2e (46) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 > VERBOSE: keys[2e] = true > VERBOSE: hid keyboard: key down scancode=2e (46) mod=00 > VERBOSE: input: UHID input [1] 00 00 2E 00 00 00 00 00 > VERBOSE: keys[2e] = false > VERBOSE: hid keyboard: key up scancode=2e (46) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 > VERBOSE: hid keyboard: key up scancode=e6 (230) mod=00 > VERBOSE: input: UHID input [1] 00 00 00 00 00 00 00 00 AltGr works completely fine in scrcpy with the --keyboard=sdk option, however. A recent-ish comment in this issue #4725 describes a similar problem to mine.
