[libxml-devel] Disabling substitution of UTF-8 chars with entities

[Dan Janowski]

The handling of encoding is not coherent in the extension, as my last  
patch on the topic illustrates. While I have no doubt that there are  
issues to resolve, in this particular instance I do not get the  
result you do.

Anyone wanting to look at the way encoding is handled is welcome to  
make a recommendation.
