  Htttpheader is for web page an not attachment IMO

 When you click on the link the browser makes an HTTP request (with
 headers) without knowing (or caring) what the response may be (HTML,
 text, binary, etc.). The server (XWiki in this case) sends the HTTP
 response **with headers**, because the headers tell the browser what
 to do with the response. The Content-Type header tells the browser
 that the response contains text content. The Content-Type can also
 specify the encoding. If no encoding is specified then the browser
 will attempt to detect the encoding (or use some default / configured
 encoding) which may not be the expected encoding, like in this case.

 XWiki needs to specify the right encoding in the Content-Type header. 
 Problem is that XWiki does not really knows it, not in a generic way.

 Then, please, must I report an issue?

My use case here: we frequently use plain-text files as exchange media for
some sets of simple information that always content accented vowels and ñ
(Spanish names and surnames and institutions' names). In several ways we
promote the use of UTF-8 encoding all along the "chain of producers" of
such files. People accessing then as attached files to XWiki pages
depicting a snapshot at a given time of, for instance, the composition of a
group. Those users occasionally use their web browsers to access that kind
of files. From here, we receive frequent complaints about garbled files.
The solution is so simple as to manually change Text Encoding in the web
browser to UTF-8 or set it by default. But this is out of our scope to
control such settings! Thus, it will be great if we can send that
information to the client, to the browser.

Follow this discussion is no clear to me if the response sent by XWiki must
or can include that information when responding to calls asking for
attached text files. Mustn't it?

Thanks for your time!

 I've to manually   select UTF-8 encoding the read it correctly or select
  UTF-8 as default encoding for the  
browser.

 Please,   is it possible to control the encoding used by a browser to
  display
  an attached text file from   XWiki server
side?

   Thanks!
