When Azeri sentences are displayed on the homepage in the "latest contributions" list, the letter "ə" is taller than the other letters. It appears to be in a different font, or something such. Either way, it is not supposed to be this way. When one opens Azeri sentences individually though, the display is fine.
I can see it too, but can you provide a screenshot just in case? This problem is likely due to font substitution. We tell browsers to use a certain font to display text on the site (which happens to be Trebuchet MS), whereas this font may not include glyphs used in Azeri (and many other languages), so it fallbacks on a different font only to display "ə". Such font mix can result in height differences especially in small sizes, and style differences. One way to work around this problem is to use webfonts. We talked about that some weeks ago https://github.com/Tatoeba/tatoeba2/issues/684
How do I post the screenshot, when there's no "upload image" here? Do I have to upload it online and then post a link?
Anyway, if font substitution is the problem, please find another more "standard" font that includes all glyphs of all languages. I've noticed such problems in WinWord documents myself, but when I select something like Arial or Tahoma, all the glyphs become normal. I haven't tried Trebuchet MS.
You can use other sites like imgur.com for example.

Thank you for the suggestion. Here is a screenshot showing a couple of Azerbaijani sentences with a less than elegant display.
This seems to be a problem with DirectWrite rendering, as I see this problem on Google Chrome and Internet Explorer. I don't use DirectWrite on my Firefox, and it renders just fine: http://i.imgur.com/geoHM96.jpg (I use MacType for font smoothing)
Edit: Yep, re-enabled Direct2D on Firefox and the text changed to the larger ə. If I'm not mistaken, font hinting is at play here. I wonder if there are any settings for DirectWrite's font rendering anywhere.
