I used APL many years before I even knew about K but I like them both (I don't have much experience with J). K is a simpler language than APL and it would be not fair to call it just a "transliteration into randomly chosen ASCII characters". IMHO its notation is well chosen. To me it is the Scheme of array programming languages. I looked at the kparc.com site "beagle3" referenced and it seems Arthur Whitney is continuing to distill the language. Regardless, it is a joy to use either language. Especially after having to look at baroque C++ code all day long.
