Have you looked into whether there are any Hanja (Chinese characters) which would be sufficiently expressive to warrant supporting as an alternative way to represent keywords?

Perhaps look to APL for efficient ways to represent math concepts/structures?

I personally don't know Hanja at all, and I think that's common for most younger Koreans. Korean did borrow from Chinese characters historically, but it's similar to how English was influenced by Dutch, German, French, and Latin — each language developed independently.

Korean has its own pure Korean words (순우리말) as its foundation, and borrowed some Chinese-origin vocabulary on top of that.

Hangul was specifically created so people wouldn't need to learn Chinese characters.

So Han's keywords use native Korean words where possible — it fits the spirit of Hangul itself.
