Tilde character ~ is not displayed in terminal using Belgian keyboard layout

• VSCode Version: 1.3.0
• OS Version: Mac OS X El Capitan 10.11.5 with Belgian keyboard

Steps to Reproduce:

1. Open Integrated Terminal (View > Integrated Terminal)
2. Type cd ~ + Enter

The tilde character (~) is not displayed.
$ cd

Copied from original issue: microsoft/vscode#9008

• Does it show up if you hit ~ multiple times?
• Does it actually input a ~ or skip the character (does the cursor move right when you hit ~, what does tab completion do when you type cd ~/?

• The tilde does not appear even if hit multiple times.
• The cursor does not move. cd ~/ is inputed as cd /

It is a keyboard layout issue: if I switch to the US keyboard layout, I can type ~. On a Belgian keyboard layout, I need to type alt+n followed by a space to produce ~. In the code editor, ~ appears. In the integrated terminal, ~ does not appear.

If I copy cd ~ from the code editor and paste it in the integrated terminal, it works as expected.

I have the same issue with a german keyboard on macOS(OS X 10.11.1).

• OS X 10.11.1
• Version 1.3.0

Thanks, I think this is to do with lack of AltGr support (#7061). Please confirm 😃

I am using a MacBookAir with a Belgian keyboard layout:

There is no AltGr key on Apple keyboard layout.

@pierredewilde if possible, could you setup https://github.com/sourcelair/xterm.js and check to see if this reproduces in the demo? This should get it up and running easily:

git clone https://github.com/sourcelair/xterm.js.git
cd xterm.js
npm install
npm start # I think this needs node <= 4
# open browser at http://0.0.0.0:3000

Yep, same issue after installing and running xterm.js: no tilde appears.

BTW, you don't need node <= 4. Tested with node 6.3.0.

I can reproduce on Ubuntu, ~~ types a single ~ and ~[space] types a single ~.

@pierredewilde this also happens in the other programs I tried it out in? (Chromium and gedit)

[pierredewilde]

It is not the case on Mac with international keyboard: ~~ types nothing and ~[space]types a space. ~ never appears in integrated terminal.

This issue is specific to integrated terminal. It works as expected anywhere else (Terminal, Chromium, ...).

I think this was fixed with improved alt support in 3.2.0 https://github.com/xtermjs/xterm.js/releases/tag/3.2.0

Working on Windows with an Azerty keyboard, typing Shift + F4 creates the tilde straight away, for me.
