Hello Francis,

You are right, the charset map is missing and specified in the nginx log error file:

/2019/08/02 12:53:42 [error] 19151#19151: *28013 no "charset_map" between the charsets "UTF-8" and "iso-8859-1" while reading response header from upstream, client: .../

I have found 3 charset maps in my nginx default install, but none for iso-8859-1 to utf8 conversion:
koi-utf, koi-win, win-utf

So I tried in http with empty charset_map:
        charset_map iso-8859-1 utf-8 { }
But special characters like é are displayed with ?

Where to find a charset_map?

Thank you for your help,
Vincent.

Hi there,

I have specified charset and overried_charset on both server and location
and yet, it was still sending headers in UTF-8.
What does the error log say?

Is there something like

   no "charset_map" between the charsets "utf-8" and "iso-8859-1" while reading 
response header from upstream

there? Because that could explain why the conversion does not happen.

On Apache we can do:

<VirtualHost mywebsite.com:80>
...
     Header set Content-Type "text/html; charset=iso-8859-1"
</VirtualHost>

How to do the same on Nginx?
I think that that Apache config will set the Content-Type header
on responses it sends; but will not do anything to actually make the
response body be valid iso-8859-1.

The nginx "charset" module expects to modify the response body if
necessary.

You can try adding a charset_map (http://nginx.org/r/charset_map) --
either a full one that maps between the one-byte iso-8859-1 values and
utf-8 values that differ; or just an empty one and let the &# conversion
happen instead.

   charset_map iso-8859-1 utf-8 { }

or include extra pieces like

   E9  C3A9 ; # LATIN SMALL LETTER E WITH ACUTE

if you want explicit conversion.
