Invalid character in SureFire xml test report

[0xE1E10]

Affected version

3.5.5

Bug description

This is a dup of #2961. It seems to be closed because they could not provide repro file. I am able to reproduce this in an open source test. https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/CsvFunctionsSuite.scala#L266 The test is expected to fail and produce lots of errors from the exception. Offending portion:

	CsvFormat:
		Comment character=#
		Field delimiter=,
		Line separator (normalized)=�
		Line separator sequence=�
		Quote character="
		Quote escape character=\
		Quote escape escape character=null

Notice the 0xFFFF in in separator. That print out comes from here. https://github.com/uniVocity/univocity-parsers/blob/7e7d1b3c0a3dceaed4a8413875eb1500f2a028ec/src/main/java/com/univocity/parsers/common/Format.java#L220 Every time there's an exception, it tries to print out the current config. Printing non-printable binary strings on screen is a questionable practice that could really mess up someone's terminal. But I guess we shouldn't choke on it neither.
