I really don't like the accented characters that have a different height than their non-accented counterpart.
Linguistically, accents should be kept in uppercase French, but it's very common to skip them (Most people think that it's an error to keep them) Especially when there is not much room, like in game that plays in 320x200.
Here are 2 rather obvious cases :
(dégâts, équipage, équipement)
(énergétique, fumée)
Here I've tested reducing the entire fonts to match the accents' sizes :
The words look much better. But I can't say it's overall better, because the originals looked... well, bolder. I attach the font files to this post, in case somebody wants to see for himself.
I think I'm going with a 2nd option : to keep copies of the fonts that replace the accented uppercase vowels with their non-accented version.
