Thanks for your input, Yarko. I've read the articles you mentioned and I understand UTF8 better now. You are right about the 3 byte assumption. It's a pretty safe bet for my purposes. I hope the project I'm working on will be shaping up in the coming months, and that I'll have enough news to share about the progress. Anyway, as I'm only beginning to work with web2py, I'm going to have quite a few questions to ask.
