Shift[ shortcut stored as Shift{, making it unusable

[esv]

I'd like to use Shift+[, however, in the Interface→Shortcuts when I use this combo, it gets recorded as shifted twice, i.e., as Shift+{ instead of Shift+[
This makes the shortcut unusable as you can't enter the double-shifted Shift+{
The same thing happens with Shift+123..., gets recorded as Shift+!@#, etc

yes but it works here (french keyboard). Which layout?

English US layout

But it seems I was wrong about P, just tried it again it a couple of layouts and alpha-keys seem to work fine, so maybe it's only symbols that are special
Tried with 123... and that also fails with !@#...
