I came upon some encrypted text that I'm trying to decypher. I think it is PK because of what I can make out. I don't know much about encryption. I've been googling the hell out of PK but it didn't come with a key so I'm lost. Here it is.

Code:
PK
 	   ýµé.}Y÷ì"         TEXT.txt:`i\²bäWÚZ(ôÆ¡º³e%_B Þp¢h°Ûï‚jêPK}Y÷ì"      PK 
 	   ýµé.}Y÷ì"                €    TEXT.txtPK      6   X
I'm thikning it is PK because of the key words in it. I'm lost though.
