Xdebug 2.0.0beta4 / PEAR::XMLParser

Last night I released version 2.0.0beta4 of Xdebug which fixes a small number of bugs. In the next couple of weeks I hope to fix all other bugs, and implement the features that I would like to have in Xdebug 2.0.0.

While getting the release ready I spend some time looking at the new PEAR installer, and encountered some interesting problems with how the PackageFile and XMLParser handle UTF-8 and XML. In PHP 5 the XML parsers output always UTF-8, which was not taken into account and because of misunderstandings they suggested to use entities for weird characters, such as the norwegian "æ". But entities are HTML features, which do not exist in XML - so this didn't work properly either. I cooked up a small patch which should make "pear convert" and "pear package" deal with UTF-8 and non-ASCII characters in a more proper way.
