Under section 1: "Guide Assumptions"
It would be nice to write that the text editor you MUST use throughout the tutorial will save/understand UTF-8 format.
I was using emacs for some edits and the osx default for others (TextEdit).
I got to the section on editing the layouts (6.8) and tried TextEdit and it asked something about rtf that I ignored and said ok... and re- wrote parts of the file to ensure the file didn't work!
I found the problem quickly thanks to Section 14: Gotchas, but when starting from scratch it would be nice suggestion/warning relating to editors in the first section that people are likely to read. For more experienced developers, it won't be a big deal but if someone is starting totally from scratch, it might just turn them off if the getting started tutorial causes problems.
