What have I overlooked?

The principle is that you don't need to know: it's an internal flag, and you just need to trust that strings will behave as they should. The intent is that when the UTF8 flag is turned off, this is purely an optimization that allows the internals to do various things in a simpler, faster way. So that's why the docs aren't littered with discussions of what effect each operation has on the flag.

Do you have a specific reason for wanting to know the state of the flag in particular cases? I'm sure we can help answer questions about specifics.
