Hello,

• What version of Go are you using (go version)? go version go1.3.3 linux/amd64
• What operating system and processor architecture are you using? Debian Wheezy (Linux 3.16.0-44-generic x86_64)
• What did you do? I ran an app which parsed a third party XML file.
• What did you expect to see? The parsing should work and the data should be extracted from the file.
• What did you see instead? An error: "xml: encoding "Utf-8" declared but Decoder.CharsetReader is nil".

As discussed in the Google group, I encountered an issue while parsing an XML document claiming to be Utf-8 encoded, so neither UTF-8 nor utf-8 as expected by the encoding/xml library.

This document specifies that "XML processors should match character encoding names in a case-insensitive way".

I plan to propose a patch doing just that, as soon as I install the golang dev tools (it is kind of my first meeting with Go).

About the implementation, would you just write a simple comparison such as strings.ToUpper(enc) == "UTF-8", or would you prefer using something like the charset lookup function?

Thanks.
