Same problem. I think you should escape the letter and type the rest

Hi,

Hope you are doing well.

Students from states such as Assam, Bihar, and Jharkhand are eligible for a central scholarship offered to college or university students, according to the NSP's official website. In the application form, they must include their Roll Code as well as their Roll Number. If your roll code is 12345 and your roll number is 67896, you must enter 12345-67896, or 12345-67896. (Roll code - Roll Number). If you continue to have issues, you can contact the help desk listed on the official website. For additional information, go to the official website and search for updates on the left hand side: https://scholarships.gov.in/

Hope this helps.

Good Luck!
