What is the use of the .utf8@euro locales?

[Gonzalo HIGUERA DÍAZ <gonhidi@gmail.com>]

Hello everybody.

I was wondering whether there is any difference between the .utf8 and
the .utf8@euro locales.

I thought @euro was used initially so that classic character sets
(such as Latin1) would not be trampled by modified ones made in order
to incorporate the euro character and other minor modifications (for
example Latin9, a euro-including Latin1 modification). However,
Unicode/ISO-10646 (and thus UTF-8), incorporates the euro sign, so I
am at a loss as why this tag is needed. What am I missing?

Thanks.
