This statement is incorrect in 2 ways.
1. The letters m and K are two of more than 20+ possible letters that can end these sequences.
2. Inside 's , OR is already assumed, so they are also looking for sequences ending with | which is not correct.
This : [a-zA-Z]
This resolves the "OR" issue noted above, and takes care of all sequences, as they all end with a lower or upper cased letter.
This ensures 100% of any escape code 'mess' is removed.
