Eev doesn't run well on Doom Emacs

I've tried to use eev with Doom Emacs and I've failed so miserably that I decided that:

Sorry, I can't give support to eev on Doom Emacs now -
please try eev on Vanilla Emacs first, then try to port
to Doom the things that your learned on Vanilla Emacs,
and then please help me!!! 😢😭😖

My notes on Doom are here. Here is a partial list of my main problems with it:

1. The prefix `M-h'

Eev uses the prefix M-h a lot - see the screenshot below; click to enlarge it - and Doom uses M-h for something else (I don't remember what). I tried a solution in two stages: in the first stage I used this trick to make M-n behave as my M-h, and in the second stage I would disable Doom's meaning for M-h and I would make M-h behave as in eev... but I was never able to reach that second stage. =(

2. The standard-display-table

Eev uses this code to set glyphs for the "*" and for the green "«»"s:

(find-eev "eepitch.el" "glyphs")
(find-eev "eev-anchors.el" "glyphs")

In Doom many modes override the standard-display-table with other display tables, and this makes the "*"s be displayed as "^O"s and the "«»"s be displayed in non-green. I guess that this is due to some kind of "display whitespace" mode, but I wasn't able to find a fix. I have some very messy notes on that here.

This bug makes eepitch blocks ugly and anchors hard to see.

3. Company and vertico hide some command names

A friend of mine - Vagner - told me that both Company and Vertico don't show all the commands of eev in the list of options for `M-x'. We tried to report a bug - this one - but we didn't solve the problem.

(More soon!)
