Can anyone explain how to read:

'\\u0000'..'\\uFFFD' - specialCharacters
It is part of Number Format Pattern Syntax:
pattern := subpattern{;subpattern}
subpattern := {prefix}integer{.fraction}{suffix}
prefix := '\\u0000'..'\\uFFFD' - specialCharacters
suffix := '\\u0000'..'\\uFFFD' - specialCharacters
integer := '#'* '0'* '0'
fraction := '0'* '#'*
found at http://java.sun.com/docs/books/tutorial/java/data/numberpattern.html
Thanks! Emma Peel

Greetings Mrs. Peel,
That link you provide has examples of building patterns for number formatters. (java.text.NumberFormat) The extra unicode characters allow you to parse and format strings with more than just numbers, for example a currency character.
One example they give is:
"\\u00A5###,###.###"
That pattern lets you parse or format string with the Yen sign in front of a series of numbers.
