Rails - Aug 2011 - Preventing LibXML from encoding all special characters to their html form?

Hi.

From what I unsertand, Rails uses by default LibXML.
When doing a to_xml, it encodes all special characters, which is useful for 
<, &, >, etc. but not really for ü, ô, etc.
First, I can''t convert them back from &#x252; to "û"
which is very
frustrating for my tests.
And I cannot manage to force LibXML not to encode all characters.

Any help? Thanks.

For those who wonder, the same encoding can be applied this way:

require ''builder/xchar''
string.to_xs

And to decode, you can do encoded_string.gsub(/\&#([a-f0-9]*);/) { |s| 
[$1.to_i].pack(''U*'') }

Thank you Builder doc!
