That's not making it unicode; you mean
fill = unicode("bar", "utf-8")
(Or "bar".decode("utf-8"), which does the same; I prefer using the
unicode builtin.)

Yes, but there's no need to. Are you perhaps using string literals
containing non-ascii chars, yet don't use the 'u' prefix? u"\xff" as
opposed to "\xff".

Do _all_ manipulations using unicode, and convert to utf-8 as late as
poosible, ie. when you're passing the result to code that expects
non-unicode data. That's basically what he was saying.
