Bug report

When using letters like Æ, Ø, Å in the menu text and menu links, the header active bottom border will not display. When using normal english characters in the text and links it works how it's supposed to.

Steps to reproduce

Use letters like Æ, Ø or Å in the nav menu text.

What is expected?

The border-bottom router-link-active should display normally with the Æ, Ø, Å letters just like it does with normal text characters.

What is actually happening?

The router-link-active (bottom border) isn't displaying when using weird characters.
