Unable to type parentheses with parens:swap_brackets setxkbmap option

[phoe]

Describe the bug
I am unable to type parentheses on https://online.interlisp.org/ which makes using Lisp somewhat troublesome.

To Reproduce
Steps to reproduce the behavior:

1. In the Linux shell, alias kb='setxkbmap -option parens:swap_brackets,ctrl:nocaps'
2. Go to https://online.interlisp.org/ and login as guest
3. Try to type parentheses (now mapped to brackets)

Expected behavior
I should be able to type parens.

After creating the alias on my Linux Mint 22 Cinnamon pc with Italian keyboard, typing { and } produces the same characters. Typing ( produces ( and typing ) produces [.

Weird, I have a Polish keymap. Are you testing this in online Medley?

[pamoroso]

Yes, I'm testing in Medley Online.

It's worth nothing that my italian keyboard is missing the { and } symbols. To get { I need to type AltGr+7 and AltGr+0 to get }.

Using setxkbmap is unlikely to ever get you the result you expect since Medley uses the X key codes (not encoded key syms), and maintains its own mapping table from the codes to the Medley physical keys. Additionally, the X keyboard mapping tools do not work as expected under macOS/XQuartz.

(and when using Medley online, you're going through your browser and NoVNC, which adds yet another layer of mapping and/or misinterpretation)

would Gingko help with a mapped keyboard?
