XMLEventReader cannot handle utf-8 byte order mark

[biswanaths]

When trying to use XMLEventReader with an utf-8 encoded XML document that starts with a byte order mark (EF BB BF), an empty iterator is returned, and an error message is printed to stderr.

test.scala

import scala.io.Source
import scala.xml.pull.XMLEventReader
val t = new XMLEventReader(Source.fromFile("hasBOM.xml"))
println(t)

Output of scala test.scala

file:/tmp/hasBOM.xml:1:1: < expected<?xml version="1.0" encoding="UTF-8" standalone="yes"?>^
empty iterator

The attached file hasBOM.xml has CR+LF newlines, but LF or CR newlines do not change the behaviour.
