Hi,
Thank you for posting your query to us.
I am afraid that I was not able to reproduce the issue. Please refer to the following steps that I tried to reproduce it.
1. Created HtmlFile which is having danish letter
2. Converted the Html file as PDF
And also I have tried the below speciifed website which contains danish text, Essential PDF generates the document without any issue.

Suba
