UTF-8 all the way through

<!-- ***** IMPORTANT INFORMATION ABOUT THE QUESTION TITLE ***** There has been a lengthy discussion about this title at the URL below. Do not make any title edits without reading it first https://meta.stackoverflow.com/questions/335327/ --> I'm setting up a new server and want to support UTF-8 fully in my web application. I have tried this in the past on existing servers and always seem to end up having to fall back to ISO-8859-1. Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL, and PHP to do this — is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur? This is for a new Linux server, running MySQL 5, PHP, 5 and Apache 2.
