Non-breaking spaces in (RichText)Labels disappearing on Windows export

Godot Version

v4.2.2.stable.official [15073afe3]

Question

`Hi! In Label and RichTextLabel nodes, I use non-breaking spaces before some punctuation marks (it’s requested in French before “:”, “;”, “!”, “?”…) and before images (in RichTextLabels), in order to avoid uggly line breaks.

It works fine when I run project (F5).
Godot F5

But after exporting project for Windows, it does not work anymore: non-breaking spaces seem to have been replaced by normal spaces.

Exe run

Any idea?`
