#1 Encoding error when reading info.xml files

[Alex Barcelo]

When opening an UTF8 info.xml (with the following line in it <?xml version = '1.0' encoding = 'UTF-8'?>).

Multinstaller doesn't read correctly special characters (like éáèà·çñ...).

In theory, wxWidgets uses UTF-8 as the default encoding, and the info.xml file is readed through the wxWidgets XML API, and wxStrings are used.
