Uppercase, lowercase, titlecase, and a file of exceptions.

The "General Category" field of the UnicodeData.txt file [2] in the
Unicode Character Database [3] for any version of Unicode categorises
each character.  The allowed values include values for "Letter,
Uppercase", "Letter, Lowercase", and "Letter, Titlecase" (as well as
"Letter, Modifier", "Letter, Other", and lots of non-letter category
identifiers).

There's also a SpecialCasing.txt file in the Unicode Character
Database for the many:1 and 1:many case mappings (such as the
lowercase 'ß' mapping to the two uppercase characters 'SS') and
locale-specific mappings (such as the lowercase mapping of 'I' to
ı, LATIN SMALL LETTER DOTLESS I, in Turkish and Azerbaijani).

Unicode Technical Report #21, Case Mappings, [1] provides more
information.
