Something I noticed:
If you imagine the chacacter ']' as a delimiter, the last few instances have the pattern {character}{repeated_number_of_characters}]
Since the character is alternating between m and k it makes me think that it could be 1's and 0's and their corresponding frequency.
i.e. mZZZZZ]k\\\]mZZ] = 1111100011 or 0000011100
This kind of scheme is similar to a compression algorithm known as Huffman encoding. I dont know if this helps but hopefully it gets the juices flowin
