CBT special characters

Hi, The issue with this C.B.T is that if the questions and answers inserted have special character like comma, < > / , ) ( # $ specially comma, . it will not display not or properly. The C.B.T should be able to accept and display this and any other special character properly. This is the issue. There are two students in the database. 1. Username: 412 , Password: one (C.B.T with special characters) 2. Username: 415 , Password: one (C.B.T without special characters) Kindly resolve this while not affecting the functionality of the C.B.T . Thank you
