18# This is a hash; keys are the property to test.
19# Values are arrays containing characters to test. The characters can
20# have the following formats:
21#   '\N{CHARACTER NAME}'  -  Use character with that name
22#   '\x{1234}'            -  Use character with that hex escape
23#   '0x1234'              -  Use chr() to get that character
24#   "a"                   -  Character to use
25#
26# If a character entry starts with ! the character does not belong to the class
27#
28# If the class is just single letter, we use both \pL and \p{L}
