Reddit.com: Let's talk Character Encoding

On Reddit.com there's a recent post with a growing discussion about character encodings in PHP applications (with some various recommendations).

I would rather not have to convert these weird characters to the HTML character entities, if possible. I'd rather be able to use these characters directly on the web page. If this is for some reason a bad idea, let me know. This might be more of a general web design question (i already posted it there), but I figured it is still appropriate to post here as well since PHP is used to pull an entry from the database, and I figured a lot of you here would know the answer to the question.

The general consensus is to use UTF8 in this case, but there's a few reminders for the poster too:

• Don't forget to make the database UTF8 too
  
• Be sure you're sending the right Content-Type for the UTF8 data
  
• an link to an article about what "developers must know about unicode/charactersets"
