I'm currently working on a customer website and stumbled on this strange error, given the HTML:
REDACTED A/S har hovedsæde i Århus (foto).
What is the character encoding being used by the file that stores the HTML? Determine the encoding, then set that encoding to be used by whatever parses the document. For example, if your document is stored with the UTF-8 encoding:
<head> <meta charset="UTF-8"> </head>
I would also try changing the font, just to make sure it's not a glyph issue, but I suspect encoding as well.
