No thumbnail in history list if spaces/accents in filename

A proper display and print :

Renamed the previous file to add some spaces (and printed/canceled it, it's only to show the problem) :

Check the fix in this PR, should take care of this. The author of this repo doesn't seem to pay attention anymore but you can update it manually per the steps I listed there.
