I'm just realizing such issues in standard LaTeX are considered to 
arise at the encoding level, and are defined in the two files (part of 
the inputenc package)

	/usr/local/teTeX/share/texmf.tetex/tex/latex/base/utf8.def
	/usr/local/teTeX/share/texmf.tetex/tex/latex/base/utf8enc.dfu

The former, for example, includes

	\DeclareUnicodeCharacter{00A9}{\textcopyright}
	\DeclareUnicodeCharacter{00AA}{\textordfeminine}
	\DeclareUnicodeCharacter{00AE}{\textregistered}
	\DeclareUnicodeCharacter{00BA}{\textordmasculine}
	\DeclareUnicodeCharacter{02C6}{\textasciicircum}
	\DeclareUnicodeCharacter{02CA}{\textasciitilde}
	\DeclareUnicodeCharacter{200C}{\textcompwordmark}
	\DeclareUnicodeCharacter{2026}{\textellipsis}
	\DeclareUnicodeCharacter{2122}{\texttrademark}
	\DeclareUnicodeCharacter{2423}{\textvisiblespace}

while the latter includes these and a lot more. Don't know whether 
that's related to both questions.

In any case the above declarations from utf8.def seem strange, as 
Unicode character 02CA is the acute accent in OS X's Character Palette, 
and neither the full-size tilde which is 007E nor the tilde accent 
which is 02DC.
