it search for a non-number, then search if it's repeated 1 or more times, then replace it by the count of them followed by the the repeated char Oha PS: could be usefull to limit the number of repeated matches, and include the numbers. but in this case numbers must always have a counter: this one will compare 2 or more char, or 1 or more if digit and match no more then a sequence of 9. in this way you can decode the data with no side-effect if strange data is used: X2AAAAAAAAAAAAAAAAAAAAAAA1111 become X129A9A5A41 A repetitions are grouped up to a max of 9, numbers are counted as repetition also if not repeated. to decode use:
Oha
