Subject: [PATCH] Fixed Unicode-bug according to
 https://foswiki.org/Tasks/Item13483

BibliographyPlugin has been identified to have Unicode-issues since
foswiki-core changed to utf-8. The in-memory-filehandle has been identifed
as the problem, so I replaced it with a simple split (consuming more memory,
but not breaking Unicode.
