do you think that the update from joomla international to joomla 1.5 will be availble or not ? is it some thing using the some upfate from 1.12 ?

One of the goals of Joomla! International is to enable Joomla enthusiasts to use Unicode UTF-8.

Since Joomla! 1.5 natively supports UTF-8, we don't have to work to that extend. But we will be glad to contribute to development of 1.5 if we can in any way.

thank you for the response, buy i did not understand.
actually i run my web site in joomla international.
my question is: can i update my website to joomla 1.5 and later version easyly ?
thank you

In response to your question about an upgrade from Joomla! International to Joomla! 1.5 easily. The answer is probably not. Joomla! 1.5 is for the most part a rewrite of Joomla! and you cannot guarantee that all of your existing components, modules, and templates from your old site will be compatible with 1.5.
