Comment 6 for bug 30562

Possible workaround for the Euro key:

Select: System - Preferences - Keyboard
      Select: 'Layout Options' tab
           Select: 'Adding the EuroSign to certain keys'
                 Select prefered key
           Select: 'Third level choosers'
                 Select prefered chooser key
now you should be able to use your chosen chooser key + chosen euro key to print the €.

This dosen't address the keymap issue but should allow users to easily type € when needed.
