The Emacs manual suggest `C-x @ h C-a' to enter `Hyper-Control-a'.
So `C-x @ c M-%' seems natural to enter `C-M-%'.  But it doesn't work.
It translates `C-x @ c M-%' to two separate key presses: `C-x @ c ESC'
(i.e. C-ESC) and `%'.  Is it possible to make `C-x @ c M-%' to work
on consoles?

This is a shorter key sequence for typing a key with the help of `C-x @'
than using `C-x @' twice which is mentioned in the manual as a currently
impossible way to add two modifiers.  Also with upper-case letters it
looks like the standard syntax for `C-M-%' without hyphens.

But there is a conflict between Shift and Super, which use the
same character modifier with different case.
