...for some definition of "behavior".

As with the "CR LF" => "LF" policy...my pitch is to take "strong bets" on trends that are going to be guaranteed to still be relevant, and put the costs of edge cases on those few who demand them.

Be sure to read over this thread regarding unicode normalization:

O noes, Unicode Normalization

This is where certain codepoint sequences are considered to make the same "glyph"...e.g. there can be a single accented form of a character with an accent, or a two-codepoint sequence that is the unaccented character and the codepoint for an accent. Since there's more than one form for the codepoints, one…
