Amire recently brought up an issue with the existing styling of the profile page [1]. Usernames in MediaWiki land are case-sensitive so the user "Jdlrobson" is different from "jdlrobson" (yes this is bizarre but this is the way it is).
On the profile page the design relies on the username being the heading and being uppercase which is misleading. To add to this, to quote Amire word for word "Furthermore, applying uppercase to any alphabets except Latin, Cyrillic, Greek, Armenian and Georgian does pretty much nothing. This means that for usernames in Chinese, Thai, Hindi, Arabic and many other languages this style definition is meaningless.
Finally, in Turkish and Azeri the letter 'i' changes somewhat unexpectedly with the uppercase transform. It's a minor issue, but an issue nevertheless. "
So I've been noticing a lot of our designs use uppercase text and it would be good to question when it is okay to use uppercase and if we should be using it (a lot of people don't like the idea that THE COMPUTER IS SHOUTING AT ME!)
Would be interested in your thoughts so this issue doesn't come up again (also would be worth documenting on the upcoming style guide [2])
