When there is no encoding attribute, REXML cannot throw an exception.

[hoge]

If REXML read a XML file in UTF-8 with some multi-byte characters in a tag which did not have encoding attribute: encoding="UTF-8", it does not throw an exception, and waits in the readline. But, in REXML 3.1.6 with ruby 1.8.7 we can processed the file.
