Intro to Unicode
Nick Patch will be giving a talk at YAPC::NA 2012 described as:
UTF-8 is the most popular character encoding on the web and has been for 5 years. Modern applications have to be developed with an understanding of Unicode, and this raises a lot of important questions since the good old days of ASCII. What is a character? … a code point? … a grapheme? This talk will bring you up to speed on character codes, Unicode, and UTF-8.
[From the YAPC::NA Blog.]
Here's the updated description of this talk, which is now called Fundamental Unicode.
