enca will however detect UTF-8 as it should

❯ # rm+unzip

❯ enca -L hr 110-original.htm
Unrecognized encoding

❯ normalizer -rfnvvv 110-original.htm

❯ enca -L hr 110-original.htm
Universal transformation format 8 bits; UTF-8
  CRLF line terminators

Expected encoding
Expected normalizer to show UTF-8 encoding after conversion to UTF-8.
Am I wrong here?

Desktop (please complete the following information):

• OS: Linux
• Python version 3.11.5
• Package version charset-normalizer==3.3.2

Additional context
I know. Html is not the same as text.
But I will document this here.

I think that "declarative mark" should not take over like that. But I am new to this encoding world....

Yes, you are correct.
What you have is somewhat edge, but problematic nonetheless.

I think that "declarative mark" should not take over like that. But I am new to this encoding world....

Not entirely true, it's more complicated than that.

Fortunately, I know how to fix this. I don't know exactly when, but soon.
The idea is to do a preg replace within the normalizer CLI if there is a declarative mark.
