Kupu Frequently Asked Questions
===============================

* Will this work with Safari or Opera or ...?

  No, Kupu will only run on browsers with the IE engine (IE 5.5+) or those
  with a Gecko engine (Mozilla 1.3.1+ and Netscape 7.1+), not on the 
  Konqueror one (which Safari uses) or on Opera or any other browser. 
  Actually Mozilla copied a feature unique to Internet Explorer, which is 
  not part of any standard, which Kupu uses. Because it's not part of a
  standard, it is not very likely any other browsers will implement it,
  although we keep hoping some day they will.

* Kupu allows users to do all kinds of things - like coloring text -
  that I don't want in my system.

  All of the kupu style functions can be turned on and off using CSS or in 
  the configuration. Additionally, the element controls can be extended to
  accomodate special needs of your content.

* Is my platform supported?

  It probably is: Kupu has requirements on the client side, but works with
  just about any web server. As long as your server supports POST and some
  server-side scripting language or CGI (to process form variables if Kupu
  is part of a form) or HTTP PUT you can install Kupu on your website or
  application.

* Why do I get all kinds of weird characters?

  Kupu seems to work correctly when you use UTF-8 as the character set for
  encoding, but gives unpredictable results when you use another one such
  as latin-1 (ISO-8859-1). Make sure to always use UTF-8 as the character
  set for incoming data and set the correct Content-Type header or meta-tag,
  and Kupu will send back UTF-8 data.

* Saving seems to work, but my browser keeps showing old stuff

  Browsers tend to store web pages a while to reduce the amount of data that
  has to be transferred. Obviously this can get in the way when using Kupu,
  so the browsers need to be told not to store (cache) the Kupu iframe contents
  on retrieval. This can be done either with HTTP headers or with meta-tags.
  For an example of which meta-tags to use, see fulldoc.html (the example
  content page).

* Does Kupu produce valid XHTML?

  Well... Kupu produces *well-formed XML*, which out-of-the-box does not 
  contain any elements that aren't allowed in XHTML anymore, and are written 
  in a form compliant to the XHTML notation (lowercase tag and attribute 
  names, attributes all have values and all values are in quotes) but it is
  theoretically possible to create constructions that are not valid according
  to the XHTML DTD. For most cases, however, the data produced by Kupu is
  perfectly usable, even after copied from another website or notorious Word.

* What about i18n?

  Currently Kupu is not adapted to i18n. The plan is to write i18n support for
  the JavaScript sources in one of the next versions (probably using XML 
  inside the HTML, a technique sometimes called 'XML data islands', to store 
  all the JavaScript strings) but currently it's not possible to convert the 
  JavaScript strings on the server without having to hack in the sources.
  Current technologies make it hard to handle i18n in a clean way on the 
  client, so therefore Kupu will at first choose to let the server take care 
  of it. Since Kupu is not dependent on a specific server, however, we can not 
  guarantee that support for your server will be available even in the future, 
  but we will at least provide infrastructure and probably also dictionaries 
  for different languages.

* What about Bitflux, Xopus, and others?

  The authors of these editors have done great work. They are superb
  applications, but the major drawback is they work in only one browser (as of 
  this writing). Kupu was created to work in both Mozilla/Netscape and Internet 
  Explorer.
