iOS external keyboard & vim normal mode: option key not handled properly

Bug reports
1

Steps to reproduce

  1. Use iOS, with an external (Bluetooth), French keyboard (or similar).
  2. Use vim-mode.
  3. In normal (vim) mode, type anything with the option key (such as {, which is obtained with option-5, with the French keyboard).

Expected result

The vim command should be executed (for example, { should move to the beginning of the paragraph).

Actual result

The character typed is inserted (and vim remains in normal mode).

Additional information

This issue was solved, at some point, for the (French) macOS keyboard (Vim normal mode: typing "{" enters "{}" instead of sending the command to Vim (French keyboard) - #10 by lebigot).
