The character encoding is not specified in the HTTP header.

[Buzby]

Any idea how to resolve this error?

If I sort out the character encoding, then it instantly says the charset encoding is wrong.

The things I feel I have to ask are:

1. Where are you getting the errror?

2. Where and what are you doing when you say this?

If I sort out the character encoding, then it instantly says the charset encoding is wrong.

This is your http header:

HTTP/1.1 200 OK =>
Date => Mon, 10 Oct 2022 08:23:31 GMT
Content-Type => text/html
Connection => close
last-modified => Sat, 08 Oct 2022 13:05:26 GMT

alt-svc => h3=":443"; ma=86400, h3-29=":443"; ma=86400

But then I don't have any character encoding specified in my http headers either so is this a real problem?

Especially as it appears the default for "Content-Type => text/html" is ISO-8859-1 anyway.
