The Latin-script writing system we use for Klingon is a phonetic transcription. We don't actually know how to "spell" anything in any native Klingon writing system.
Alas, that is no longer true. Thanks to the intervention of
certain Klingonists, Klingon has appeared in decipherable writing
on Star Trek: Discovery, in the one-to-one phonemic
alphabet invented by another certain Klingonist. This alphabet is
directly translatable to our Latin-letter transcription. We are
stuck with this most boring of writing systems being on-screen
canon, at least for the Discovery Klingons, and no
explanation of why the in-universe compilers of The Klingon
Dictionary had such a hard time understanding it.
