You would have to go through the script looking for items like
which is similar or the same as the code that actually accepts the answers.
Then you would have to use $utfdecode($1-) to alter the text entered (in utf format) to default latin characters, which can then be compared in the script.
I'm not sure what the code might look like for sending the information, but you would need to use $utfencode(<message>) to send the message using UTF characters.
