However I don't see any problem when I send it to my self, it's mu4e.
Should I escape somehow my backslashs ?

yes

In the previous mail I forget the point : this bug appears in ~org-mode~
buffers.
Do I need to forward to another mailing list the issue ?

So in a scratch buffer, with emacs -Q, here the recipe :

(add-hook 'org-mode-hook 'prettify-symbols-mode)

?\" ;; after this point prettify does not behave correctly anymore

 ;; this will be a _lambda_ symbol when it should not
(setq-default prettify-symbols-alist '(("lambda" . 955)))

(org-mode)
(prettify-symbols-mode 0)
(prettify-symbols-mode 1)

 ;; this will not be a _lambda_ symbol when it should
lambda


?\"  ;; after this point prettify behaves correctly again

 ;; this will be a _lambda_ symbol like it should
lambda
