I'm not sure who I should complain about this, the typesetters who don't do something like removing the diacritics, or adding them using the brush tool in the image manipulation software they use or the font makers for not even adding the most basic of support for, at least, extended ascii.
Of all the things to call a scanlation team out for, diacritics on a faux-foreign brand name was not one I ever expected, yet here we are. /yes, I know I'm a year late to the party, but that was the latest post, so sue me.
