IPTC and non-US characters?

[bjornkn]

I'm having problems with using non-US characters in IPTC fields.
Like æøåÆØÅ as used in Norway and Denmark.
XnView can read them just fine, if entered in other programs like LightRoom etc, but when I enter the data in XnView it ends up as an "?" .

There is also a problem displaying EXIF characters, which AFAIK can not be changed in XnView.
See attached images - supposed to show an ø, in Bjørn.

Please try XnView MP

It seems to work ok in XnViewMP
Will it eventually work in XnView too?
I was working with my brother-in-law for a hilw, teaching him some digital photo handling and adjusting, but he was using a Mac.
Somehow I prefer XnView Classic..
