iframe with 3.party html-homepage doesn't show danish letters correct.

In Website X5 v8 it worked ok, but in v9 danish letters doesn't come out right.

My v8 page, working fine:http://www.ht-bridge.dk/hjemmeside/turneringer.html

Similar page in v9, with errors:http://www.ht-bridge.dk/hjemmeside2/turneringer.html

Webpage imbedded in iframe: src=http://www.ht-bridge.dk/bridgecentral/Turneringer.html

And don't tell me to upgrade the 3.party page to html5. I don't have that opportunity.
