In my bibTeX to wiki transfers, I need to deal with accents in the way TeX does and in the way that Unicode does...

Here is the list I had:

		$output =~ s/{{/XXXopenXXX/g;
		$output =~ s/}}/XXXcloseXXX/g;
                $output =~ s/, and/ and/g;
                $output =~ s/ +/ /g;
                $output =~ s/--/-/g;
                $output =~ s/{//g;
                $output =~ s/}//g;
                $output =~ s/\\'a/á/g;
                $output =~ s/\\"a/ä/g;
                $output =~ s/\\'c/ć/g;
                $output =~ s/\\vc/č/g;
                $output =~ s/\\'e/é/g;
                $output =~ s/\\`e/è/g;
                $output =~ s/\\c e/ę/g;
                $output =~ s/\\'i/í/g;
                $output =~ s/\\'o/ó/g;
                $output =~ s/\\`o/ò/g;
                $output =~ s/\\"o/ö/g;
                $output =~ s/\\"u/ü/g;
                $output =~ s/\\~n/ñ/g;
		$output =~ s/\\'n/ń/g;
                $output =~ s/\\'E/É/g;
                $output =~ s/\\\^\\i/î/g;
                $output =~ s/\\\^i/î/g;
                $output =~ s/\\Imamoglu/İmamoğlu/g;
                $output =~ s/\\Vuckovic/Vučković/g;
		$output =~ s/XXXopenXXX/{{/g;
		$output =~ s/XXXcloseXXX/}}/g;

until I decided to have Grok try to exhaust all possibilities, so that I wouldn't have to catch omission by eye. Here's what it came up with:
