Great, thanks Michael.

I've always used AnsiString so why is UnicodeString preferable here?

So is the idea we need to specify an UTF-8 encoding for unicode otherwise it assumes ASCII format? I didn't specify the encoding with TStringList and I always seemed to get back what I wanted (maybe it sniffed the encoding from the file?).
