Handling password inputs and verification in config scripts so that special characters are allowed in passwords

[Olivier Berger <olivier.berger@xxxxxxxxxxxxxx>]

Hi.

Let's consider the following snippet from a package's config script :
            db_beginblock
             db_input critical "phpgroupware/header/password" || true
             db_input critical "phpgroupware/header/password/confirm" || true
            db_endblock
            db_get "package/header/password"
            password="$RET"
            db_get "package/header/password/confirm"
            confirm="$RET"
            if [ "$password" != "$confirm" ] ; then

If I'm not mistaken, whenever a user inputs a password containing
characters like a double quote ("), the script may fail to properly
manage such a password.

Is there any good practice, doc or otherwise guidelines on how to deal
with such cases in debconf ?

Thanks in advance.

Best regards,
