Stefan, welcome to TalkGraphics.

I am sure you have done the right things; you must ensure you click OK for all changes when working on NavBars.

Trebuchet MS is installed on my PC and the attached Trebuchet NavBar.xar renders in all major browsers including Safari.

Things to do:
  1. Check you have Trebucket MS installed as a font
  2. Run the program once as Administrator
  3. Check you are saving each change correctly
  4. Check your keyboard region and language setting is Sweden
  5. In the Xara Spell-checker, ensure the document Language is Swedish
  6. Use a Unicode Character Mapping tool like Babelmap as a safety net
