One concern I have, that might lead into rationale for the current discouragement,
is that I would hate to see a best practice that pushes a BOM into ASCII files.
One of the nice properties of UTF-8 is that a valid ASCII file (still very common) is
also a valid UTF-8 file.  Changing best practice would encourage updating those
files to be no longer ASCII.

Attached is a draft proposal for the Unicode standard that intends to clarify the current recommendation regarding use of a BOM in UTF-8 text.  This is follow up to discussion on the Unicode mailing list back in June.

Feedback is welcome.  I plan to submit this to the UTC in a week or so pending review feedback.
