what OS are you using exactly ?  this seems to work just fine for me in CrOS.

when you say "pt_PT", i'm guessing you mean "the Portuguese QWERTY keyboard layout as used in Portugal":
  https://en.wikipedia.org/wiki/QWERTY#Portugal

this is working fine for me in CrOS.  i select the "Portuguese keyboard" there (which lines up with the layout listed in wikipedia above), open a new Secure Shell window, and then press AltGr+2 and i get back @.

Windows 10, Chrome Version 63.0.3239.84 (Official Build) (64-bit), Secure Shell version 0.8.40.1.

Keyboad is that one. This is 100% reproducible. In fact, just tried now the Alt-Gr combinations don't produce the expected output, if they produce output at all. For example:

AltGr+ | Standard  | Shell-in-Tab | Shell-in-window
1      | (nothing) | (nothing)    | 1
2      | @         | @            | ^@
3      | £         | £            | ^[
4      | §         | §            | ^\
5      | €         | €            | ^]
6      | (nothing) | (nothing)    | ^^
7      | {         | {            | ^_
8      | [         | [            | ^H (backspace)
9      | ]         | ]            | 9
0      | }         | (nothing)    | (nothing)

When I wrote ^H, I meant ^?. It seems hterm is sending control characters.

this looks like a bug in Chrome's handling of AltGr keys inside of "apps", and might be outside the control of Secure Shell.  on the other hand, apps are deprecated/dead on Windows, so no one cares how well they work.

this might "fix" itself when the Secure Shell Extension variant launches.

Except for the fact that this is the only way we can SSH in corp from a gWindows machine... are you sure that this is a no one cares scenario?

BTW, AltGr+0 also doesn't work even in in-tab mode.

from Chrome's pov, yes, no one cares about Chrome Apps on Windows.  that's why we're launching an Extension version of Secure Shell in 2018Q1.

also, i'm fairly certain the Chrome Secure Shell app is not the only way you can do corp ssh.  http://go/corpssh-faq talks about putty/cmdline ssh too.

I can wait 2018 Q1 with in-tab shells. Putty is way worse...

you can star b/31225897 for updates and then redo your tests when it's ready and let me know how it goes.  i tried getting a windows vm in the past and it didn't really work out, so maybe i'll have to request a windows laptop or something :/.
