Hi,
I just encountered a strange error where a user managed to put a DEL char inside a text field. This char raise an SQL Exception in the server.
First, I really would like to know how they manage to do this ! I do not even know how to put a DEL (code 127) inside text with the keyboard. I had some case with other control char in the past too.
Second, is there a wonder way to filter these or a Javascript method to prevent them from the source, or any suggestion to handle this ?
Real users are alway a source of unpredicted challenges.
Thank,
Samuel
