212B Ångström sign should most certainly be equated to 00C5 Å in
normal string comparisons. The Unicode standard list them as
strongly (canonically) equivalent. They should thus be regarded as
unequal **only** when comparing the *raw* binary codes. The case
is the same for the Kelvin sign and K, and for the Ohm sign and
B.t.w., there is no such thing as an "Angstrom sign", but there is
an Ångström (note the spelling!) unit sign (which is the letter Å).
Quoted from http://www.si.se/english/factsheets/inventio.html:
The pioneering work of Anders Jonas Ångström (1814-74) in spectral
analysis forms the basis for this entire modern discipline. He
analyzed the sun's chemical elements, and in 1868 he published a
map of the spectral lines of nearly 100 elements. Ångström was
also the first to measure wavelengths in absolute terms. For this
purpose he introduced a basic unit, one ten-millionth of a millimeter,
later (1905) named after him.
