If there is a null character in the middle or somewhere inside an ansistring, this does not affect it's length, correct? Unless casting with pchars in play.
Reason I ask is that I wonder if it is a good idea to strip all incoming null characters for web/internet security reasons. If someone inserts a null character and they get stripped, this is safer than keeping them there and offering some compatibility in case some odd person chose to store null characters in his string. Probably that would only be used in rare cases such as a delimited file with null characters.
