I've just install the last version of PHP6 dev and I've decided to test the famous new feature, the PHP Unicode Support. I will not explain new things about PHP6 or Unicode or TextIterator, it's just my discoveries test on this features.

He steps through the process he followed - enabling Unicode support, testing various output methods (including just an echo and using the TextIterator) as well as some of the manipulation methods (next/first/current) that can be used to get certain characters out of a string.

As a result of all the noise about UTF-8, got an email from Marek Gayer with some very smart tips on handling UTF-8. What follows is a discussion illustrating what happens when you get obsessed with performance and optimizations (be warned - may be boring, depending on your perspective).

He talks mainly about using the native PHP functionality to avoid the mbstring issues that could arise by restricting locale behavior and using a fast case conversion function to handle strings correctly. The other tip involves delivery methods to those not able to recieve UTF-8 formatted content - checking their character set and responding accordingly.
