cubicweb #2522325 Content-disposition use the wrong parameter [done]

RFC6266 says

The parameters "filename" and "filename*" differ only in that "filename*" uses the encoding defined in [RFC5987], allowing the use of characters not present in the ISO-8859-1 character set ([ISO-8859-1]).

However the cubicweb code:

  1. use filename all the time.
  2. encode it in utf8 all the time.

According to my reading of RFC6266 this is wrong. We should not put any encoded content in filename and use filename* for this purpose.

This may explains some but on windows with older IE version.
