On the Ibuildings techPortal today there's a new post with the latest in their Dutch PHP Confernece 2009 sessions podcasts. This episode is Juliette Reinders Folmer's presentation Everything you always wanted to know about UTF-8 (but never dared to ask).
With PHP6 in the works and said to be fully UTF-8 compliant, the interest in the community in using UTF-8 has grown. On top of that, with PHP entering the - often multilingual - enterprise web playing field, the benefits UTF-8 can bring are getting more attention. Unfortunately most developers at one point or another run into problems implementing UTF-8.
Her presentation included some basic linguistics, client side things you'll need to consider and things to watch out for on the database side too. As usual, you can listen either through the in-page player or you can download the mp3 directly.
