Add character categorization isDigit, isLetter, etc

[leonardo@…]

For character parsing and categorization, the following functions would be useful. I'm proposing a dojo.char namespace, but I guess dojo.string would be fine too:

• isDigit(ch): True if the char is a digit: [0-9].
• isLetterOrDigit(ch): True if the char is a letter or digit: [A-Z]|[a-z]|[0-9].
• isLowerCase(ch): True if the char is a lowercase letter: [a-z].
• isUpperCase(ch): True if the char is an uppercase letter: [A-Z].
• isWhitespace(ch): True if the char is a whitespace: [s].

Notice that most of this regular expressions aren't Unicode enabled. But it would be better if they are.

Interesting, but not sure why you would do this when the Regular Expression engine is available anywhere (with Unicode support); this functionality is already a part of JS.

Closing the ticket. Thanks for the thought, though.
