Help me decode Unicode
January 29, 2012 4:29 PM Subscribe
What languages use a U with a ring on it (U+016E), and how is it pronounced? What is an "incomplete infinity" (U+29DC), and why does it need a symbol? Who uses a times sign in two circles (U+2A37), and for what? And why is a small capital psi (U+1D2A) in the Phonetic Extensions block? How do I find the answer to things like this?

Unicode is full of all kinds of bizarre and interesting things, and I'd like to know just what they mean. I'm not looking for the answers to the above questions (although it'd be helpful) so much as a resource where I could go "why is this character even in Unicode in the first place?". I want to find out who uses a specific character and what it means, especially when the given name for it is unhelpful.
I've tried looking them up on Wikipedia, with mixed results, and Google searches mostly turn up pages with the Unicode definitions themselves, which very seldom say just where the character is from. Even in cases (like U+22B9, "hermitian conjugate matrix") where I'm familiar with the meaning, I'd like to know who uses that notation for it - like, a reference to a book or paper with that symbol being used for that purpose (in this case, I'm not used to seeing that broken-plus shape with that meaning).
If any of you know of somewhere I can find things like this out, it'd be much appreciated.
