It is not a bug in DerivedCoreProperties.txt, I asked on the Unicode
mailing list:
http://www.unicode.org/mail-arch/unicode-ml/y2014-m11/0010.html
So these are actually title case as well.
That means, because of the restrictions of ISO C 99, these title
characters should be both in the âupperâ and âlowerâ character class
in LC_CTYPE (my gen-unicode-ctype.py from comment#28 does this).
