The situation seems very similar to that for U+20A4 vs. U+00A3. I was
taught at school in the UK, and I guess Australians were taught before
1966, to write the pound sign with two bars like U+20A4, and in fact I
still usually do so in handwriting. But today the single-barred version
is much more common in print in the UK. And the notes for U+20A4 suggest
that this became true also in Italy, before the Euro was introduced.
I wonder how long before the Euro will also de facto have a single bar?
