    If the RSS feed (you did not provide the URL, by the way) uses the
    arabic script, then, indeed, these readers are wrong since arabic
    characters in Unicode have the bidi class "Arabic_Letter" and should
    be rendered RTL, without needing HTML or Atom attributes (I do not
    think RSS has such an attribute.)


    IMHO, this page is wrong because it uses languages instead of
    scripts. There are also technical mistakes for instance they say "The
    language value must be in lowercase" while language tags are

    That's probably because *most* languages are written in only one
    script (azeri, for instance, is an exception) and therefore have only
    one directionality.

    But, you're right and they're wrong, directionality is a property of
    the script, not of the language.
