Ah, I see I was wrong about TextEdit on OS X 10.5, then: For UTF-8
files that it *itself* saves, then it does — despite the lack of a BOM
- open them without defaulting to a legacy encoding.

(Wonder if the the so called 'resource fork' - the meta data companion
that OS X since version 10.6 abandoned - plays into this?)

But if saved by some app (that probably doesn't add the extended
TextEncoding attribute that you mention), then TextEdit for OS X 10.5
fails to open it as UTF-8.
