# Characters Strings.
#
# The character datatype, abbreviated as char, stores letters and
# symbols in the Unicode format, a coding system developed to support
# a variety of world languages. Characters are distinguished from other
# symbols by putting them between single quotes ('P').<br />
# <br />
# A string is a sequence of characters. A string is noted by surrounding
# a group of letters with double quotes ("Processing").
# Chars and strings are most often used with the keyboard methods,
# to display text to the screen, and to load images or files.<br />
# <br />
# The String datatype must be capitalized because it is a complex datatype.
# A String is actually a class with its own methods, some of which are
# featured below.
