Description
Determines if the specified character is a letter or digit.
For a more complete specification that encompasses all Unicode
characters, see Gosling, Joy, and Steele, The Java Language
Specification.
A character is considered to be a letter if and only if
it is specified to be a letter or a digit by the Unicode 2.0 standard
(category "Lu", "Ll", "Lt", "Lm", "Lo", or "Nd" in the Unicode
specification data file). In other words, isLetterOrDigit is true
of a character if and only if either isLetter is true of the character
or isDigit is true of the character.
