Of course not.

And I think you'll find that's a rather distinct case. For all uses
that I am aware of, æ is a single letter in the alphabet. Whereas I'm
not aware of any alphabet that has promoted ligatures such as the
following to the status of a letter: ff, fi, fl, ffi, ffl, LJ. In fact, for
each of those the Unicode specification explicitly describes
approximate equivalents, such as

	ff
	U+FB00 LATIN SMALL LIGATURE FF
	...
	Approximate equivalents:
	 • U+0066 LATIN SMALL LETTER F U+0066 LATIN SMALL LETTER F

No approximation is offered at all for æ, for example.

I first ran into this problem when attempting use evince to
copy-and-paste the word "fill" out of a PDF file containing a
description of the PostScript language. My PostScript interpreter was
quite unhappy to see the word "fill" instead of the expected "fill",
and acroread correctly performed the copy of "fill" to the string
"fill" to be pasted.
