I'm Chilean, meaning that my first language is Spanish. I'm using Opera 41; the text is already a bit blurry in general, but I can deal. What's really bothering me is how characters such as á é í ó ú Ñ ñ look in the browser. I've noticed it happens with the ç character too, but we don't use that one.
It's like the letter-spacing of those specific characters gets screwed up. http://imgur.com/a/MBMZi
(Note, the highlight in the words "esté usando" is there because I DID type it with a space between the words, when I select the text it's there, but it looks like it's not.)
I realized too that this doesn't happen with all text in Opera, it happens with just the random paragraph text font that Opera uses (And yes, I've tried to font configuration a thousand times, doesn't make a single difference).
All these characters conflate with the one immediately next to them (Including dots and commas) and it's really upsetting to me. I've tried to find a way to solve it but I've come empty handed.
