Question Nginx not use charset UTF-8 for xml...?

[Azurel]

Server operating system version

AlmaLinux 8.8 (Sapphire Caracal)

Plesk version and microupdate number

Plesk Obsidian Version 18.0.53 Update #2

I verified a XML file with w3.org and get back:

This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
Your feed appears to be encoded as "UTF-8", but your server is reporting "US-ASCII"

XML files are served by nginx and not in utf-8? What with Javascript? How I can change that in plesk?

That's something you define in your XML file. Like:

<?xml version = "1.0" encoding = "UTF-8" standalone = "no" ?>

 

[Azurel]

This is what the line says. In the file utf8 is specified (with encoding="UTF-8"), but the XML-file is sent as charset US-ASCII.

What are the headers of the server response when you request the XML file?

 

[Azurel]

Content-Encoding: br
Content-Type: text/xml
Date: Wed, 19 Jul 2023 08:24:21 GMT
Etag: W/"64b6f061-6009"
Last-Modified: Tue, 18 Jul 2023 20:04:49 GMT
Server: nginx
Vary: Accept-Encoding

another servers response here with

Content-Type: application/xml; charset=UTF-8

 

[kpushkarev]

So, you need to fix the Content-Type header. You can use something like AddCharset UTF-8 .xml in Apache config (e.g. in .htaccess) if you have Apache behind nginx or charset utf-8; in nginx configs.

 

[Azurel]

Should this not be the standard, for XML, HTML, ...?

 

[kpushkarev]

Not all documents in the world are in UTF-8, so forcing that on web server level by default is risky.

 

[Azurel]

forcing that on web server level by default is risky.

Is it? Why? UTF-8 includes US-ASCII which is default?

Is it? Why? UTF-8 includes US-ASCII which is default?

Encoding may be set in the document itself and different from US-ASCII or UTF-8.
