What we have here is a non-uniqueness in the unicode standard (U+00c5 vs.
U+212b), and in LaTeX as well (\AA vs \r{A}).
This double non-uniqueness cannot be fixed properly by just exchanging LaTeX
macros in lib/unicodesymbols: With the proposed patch, tex2lyx would
translate \AA in the desired way, but it would not translate \r{A} in the
desired way anymore.
Since lib/unicodesymbols does not really support non-unique symbols, it is
better to add special code for \AA and \aa to tex2lyx IMHO. Then it does not
matter anymore whether U+00c5 maps to \AA or \r{A} (but I would keep the
current mapping, since it fits more nicely to the other symbols with rings).
