It’s part typographic Wikipedia … and part glyph palette on crack.
The decodeunicode project is collaborative information gathering, powered by a typographically inclined community. Developed at the University of Applied Sciences in Mainz, Germany, decodeunicode facilitates the documentation, research, and understanding of the 98,884 distinct graphic characters defined in the Unicode standard.
Sound geeky? Well yeah, it kinda is.
Basically, the decodeunicode site lets you browse through every single one of those characters. Fonts that come pre-installed with modern operating systems can contain literally thousands of characters and symbols, many unfamiliar to the average user. How does your computer display Kanji ideographs and complex Arabic ligatures? Where can you find the currency symbol for Mongolia? When would someone even use an ogonek anyway? Answers to these types of questions are what this project plans on providing.
