Description of Problem:

when trying to edit an XML file with encoding "UTF8" i.e header: 

< ? xml version="1.0" encoding = " UTF8 " ? >


mono throws the exception: 

System.ArgumentException: Encoding name 'UTF8' not supported
Parameter name: name
  at System.Text.Encoding.GetEncoding (System.String name) [0x00000] in
<filename unknown>:0

<filename unknown>:0 


whereas the .net implementation has no issues loading the file

Steps to reproduce the problem:
1. generate a XML file with header < ? xml version="1.0" encoding = " UTF8 " ?
>
2. try to load with XmlDocument.Load()


Actual Results:

the stacktrace above

Expected Results:

the xml document should have loaded normally

How often does this happen?
