UTF-8 Support broken from ports update

[Love von Melen Ekman]

Hello questions!

In late january I updated all ports (portmaster --no-confirm -d -G -a) and
after the update I lost UTF-8, wide character compatibility in irssi, vim
and mutt and such-like.

In fact, I can write åäö in terminal (echo manages to print them for
instance) but I am unable to read the åäö that other systems write and also
when I send my UTF-8 characters to other systems they only seem them as
garbled.

Using systemwide login.conf as such:
        :umask=022:\
        :charset=UTF-8:\
        :lang=en_US.UTF-8:

and env tells me

MM_CHARSET=UTF-8
LC_MONETARY=sv_SE.UTF-8
LANG=en_US.UTF-8

Ideas?

Cheers,
Love
