Comment
These functions exclude
questionable punctuation,
such as +, $, and =, in the
class of regular
[[:punct:]]
expression functions.
These functions recognize
accented letters in the
appropriate character
classes, such as :upper:,
:lower:, :alpha:, and so on.
These functions do not allow
the backslash character (\) in
a regular expression, even if it
is inside a character class [].
You must escape it by
prefixing an additional
backslash (\\). ColdFusion 5
does not require you to
escape a backslash in this
case.
REFind does not return the
proper value when running in
a Japanese locale and using a
double byte-character as the
search string.
