S3_SAFE_CHARS doesnt works for æ

[terkin]

When I am trying to get object from S3 like /unsafe/Udlejemægleren.jpg I got error even that I have S3_SAFE_CHARS=æ {"message":"Get "https://Udlejem%C3%A6gleren.jpg": dial tcp: lookup 546a3193-8448-4e58-862c-0afc95ab39d4 on 10.0.0.2:53: no such host","status":500}

but it works fine if I try to access it like /unsafe/https://s3-url.com/Udlejemægleren.jpg

its bug or I am doing something wrong ?
