Wezterm: German keymap on Windows 10 does not work correctly

[mardukbp]

Describe the bug

In the German keymap some characters (like |) are inserted pressing the modifier key Alt Gr. This does not work in wezterm.

Environment (please complete the following information):

• OS: Windows 10
• Frontend: OpenGL
• Version: 20200517-122836-92c201c6

To Reproduce

1. Activate the German keymap in Windows
2. Fire up wezterm
3. Press Alt Gr + <

Instead of inserting |, nothing happens.

Setting RUST_LOG=debug reveals that the problem is that the rustyline crate uses Emacs mode by default and interprets Alt Gr as Meta and it complains that Alt Gr + < is not a recognized Emacs command.

Configuration

return {
   font_size = 16.0,
   hide_tab_bar_if_only_one_tab = true
}

Expected behavior

Pressing Alt Gr + < should insert |.

@mardukbp I think I've figured this out. I've pushed a commit that seems to resolve this for me.

You'll be able to download a build from here when it completes:

Please let me know how that works for you!

@wez I can confirm the provided build does resolve the windows AltGr handling
