Hydraglass The logo makes use of a somewhat "shapely" e, which to me is suggestive of the accent that belongs there. If you look at their "About Us" page, they mention their founder, Mr. Léger. If you want to include an accent in an article mentioning them, let it at least be the right one. Otherwise, follow their lead, as on most pages of the Web site, and leave it out altogether. As an English-language publication, I would be more inclined to forgive that, than use of the wrong one.
