User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Firebird/0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Firebird/0.7

Opening XML content with missing encoding declaration doesn't flag an error
(instead, it seems that Mozilla just assumes something like ISO Latin). Instead,
an error should be displayed (this ois a fatal XML parsing problem!).

Reproducible: Always

Steps to Reproduce:
(see attachment)

Actual Results:  
XML source tree is displayed.

Expected Results:  
Display parsing error.

Nor should it.  The encoding decl is optional for UTF-8 content.

Now this content is not UTF-8, and we don't flag _that_ as an error.  That's a
bug.  I thought we had it filed, but we don't seem to.

Just confirming: yes, this is about non-UTF-8 content without XML declaration.
