Of course, the reason why they have different code points is not that
they might look different (this is just a coincidence, caused by Pango
rendering them from different typefaces). The reason the separate ohm
sign exists is presumably a roundtrip compatibility requirement
(i.e. there is some older character encoding that has it). In fact,
the Unicode standard says that the preferred representation *is* the
Greek capital omega. There aren't different Unicode character for the
Latin letters used for ISO units either, so there is no real reason to
use a separate character for ohm in new applications.
