Yup, that's the first link for me too.  And it has the answer Roedy wants.

If you're looking for information about meta-characters in regex 
character classes, shouldn't that be obvious?

At first I might try is something more specific, but after 12+ years of 
Google use, it's kind of obvious to also try a more general search word 
list.  Trying out five or ten different searches does not take 15 
minutes total, as Roedy claimed.

Yes, I realize that some things are hard to search for, but this is 
certainly not one of them.  And for me personally that was the first 
search I tried after reviewing the Java Pattern page.

Also, I'm surprised no one has pointed this out.  From the Java Pattern 
page:

"For a more precise description of the behavior of regular expression 
constructs, please see Mastering Regular Expressions, 3nd Edition, 
Jeffrey E. F. Friedl, O'Reilly and Associates, 2006."

Chris folks, it even points you at the very authoritative source you 
claim to be looking for.  Did anyone ever try reading that book?

SOME things on the web or in computer science are esoteric and hard to 
find more information on.  This is not one of those things.
