Re: UTF-8 signature / BOM in CSS

That's one way to see it, but another way is to consider it a character 
and to bring it squarely in the grammar of a language, like I proposed 
recently for CSS:

  EncodingDecl = [BOM][@charset=<foobar>]

with the additional constraint that EncodingDecl must occur at the start 
of the stylesheet.

The BOM is a pretty mysterious beast for many, with a somewhat fuzzy 
status, and the above has the advantage of making it and its role 
explicit, instead of living in a some strange layer somewhere between 
byte sequences and character sequences.
