Odd error in current version of SP caused by XML comment in config.

[Mike Flynn]

I am testing the current windows version of Shib SP.  I brought over a bunch of stanzas for metadata from my 2.3.1 prod version and I get this error:
C:\Users\Administrator\Desktop>C:\opt\shibboleth-sp\sbin\shibd -check
2015-02-20 13:39:40 ERROR XMLTooling.ParserPool : fatal error on line 1, column 1, message: invalid byte ' ' at position 2 of a 2-byte sequence2015-02-20 13:39:40 ERROR Shibboleth.Config : error while loading resource (C:/opt/shibboleth-sp/etc/shibboleth/shibboleth2.xml): XML error(s) during parsing, check log for specifics2015-02-20 13:39:40 FATAL Shibboleth.Config : caught exception while loading configuration: XML error(s) during parsing, check log for specifics
configuration is invalid, check console for specific problems
Turns out this error was caused by this character: ö
Moreover, that character was inside a comment like this: <!-- The Name of the enterprise metadata öwner -->.  2.3.1 had no issue with that character.  Is this a bug?  Just curious.  I can get rid of the umlaut blessed O and the issue is resolved but was curious why this occurred.
