Your certainly right, non-breaking spaces are valid unicode, but for
my purposes I need to treat all whitespaces and non-breaking spaces as
the same thing and I need to collapse all them all between non
whitespace characters.
So I wrote a static method that I put in my String utility class that
converts non-breaking spaces, figure spaces and narrow non-breaking
spaces to spaces. I figure if it's useful now, it will be useful in
the future.
After I run the string through the static conversion method, I then
use the replaceAll("\\s{2,}", " ") to collapse and convert all
whitespaces to a single space between non-whitespace characters.
Thanks for everyone's help, character manipulations are a weakness of
mine, but I'm starting to get it.
