Broken links in Org mode

Question

I'm stuck with a broken link problem. I installed Manjaro Linux and Emacs 27.2. I use org mode for my every day planning at work. I have a lot of internal links to open PDF, ODT, PNG files, etc.

Since my new install, the links don't open anymore. The path in the buffer is all messed up and I think it's related with my language environment (French) but I'm unable to find a solution.

Here is the path in the buffer and this is the good path: /home/martin/MEGA/.CMDP/4.Departements/Urgence/Fluidité/Rapport intervention Anna_Laberge.pdf

Any clues for a solution?

Result for the locale command:

LANG=fr_CA.UTF-8
LC_CTYPE="fr_CA.UTF-8"
LC_NUMERIC=fr_CA.UTF-8
LC_TIME=fr_CA.UTF-8
LC_COLLATE="fr_CA.UTF-8"
LC_MONETARY=fr_CA.UTF-8
LC_MESSAGES="fr_CA.UTF-8"
LC_PAPER=fr_CA.UTF-8
LC_NAME=fr_CA.UTF-8
LC_ADDRESS=fr_CA.UTF-8
LC_TELEPHONE=fr_CA.UTF-8

Answering a question in a comment: This command work fine and it open my document: /usr/bin/xdg-open '/home/martin/MEGA/.CMDP/2.Comites/Obligatoires/CEAMDP/Départements/MédecineGénérale/Méd. fam. crit explicites 24 novembre 2021.pdf'

org mode version 9.4.4 emacs 27.2

Just found curiously that the link work with a right mouse click...but not with the left one Weird...
