Is not the all characters match logic like this
1. Be sure to meet the license plate number
2. The prefix and suffix must match
3. Text order must be correct
EX :
If choose all 1 mismached character
Registration plate is ABC-123
Than
A8C-123 (OK)
ABC-13 (Word count does not match)
ZBC-123 (The prefix does not match)
ACB-213 (The order does not match)
