cannot type some characters with mintty

Question

Using mintty as terminal, running it like this :

C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico -

I cannot type characters like ~,[,{ ...

But I can type all those characters on the windows cmd terminal, and on cygwin default terminal, running cygwin.bat :

@echo off
C:
chdir C:\cygwin64\bin
bash --login -i

What's doing mintty on my keyboard ?

I use mintty all the time without issue. What keyboard does your Teamviewer come in with? This feels like a "misconfiguration" when teamviewer is in the middle. – Ruthenium

What you mean by the "cygwin default terminal"? Cygwin's default terminal is MinTTY. – Jackquelinejackrabbit

I have a similar issue, except that the keys also don't work in the windows console window running bash either. When I type Ctrl-V and then one of the keys, I notice that they are all prefixed with an ESC character; e.g. the sequence Ctrl-V \ results in ^[\ (where ESC is displayed as ^[). Did you find any clue to what the reason may be? – Scrimmage

Oh, I should add that (1) the issue persists even with a shell started via C:\cygwin64\bin\bash.exe --noprofile --norc --noediting, which should disable readline and prevents bash from executing (some) startup scripts; and (2) that Windows programs like Notepad++ or cmd display the characters just fine, which seems to indicate a cygwin or bash issue. – Scrimmage

Interesting thing is that if you type the normal key (without modifiers like AltGr) several times and then with the modifier it will print the character you need – Aziza
