That’s still likely a mistransliteration (or maybe because those are proper names), but Klingon has only “q” and “Q” (which depending on the capitalization are pronounced differently, treated as different letters), technically there’s no “K” in the Klingon alphabet, you can see it in the pIqaD:

Similar as with the “f” from “Worf”, there wouldn’t be a straight “non-destructive” way to write it in Klingon.
