I have no idea what the GP meant, but fwiw: Korean is written using an alphabet not entirely unlike Latin (for the purpose of this discussion), except that when written, several letters are layed out together in syllabic blocks. Those blocks appear superficially similar to the characters used to write Chinese languages and much of Japanese. However these are logograms, that is each character represents a whole word (simplfying again - in truth many of these characters can be broken apart into components, but they're not assembled from phonograms like Latin or Korean characters; further, Japanese writing also uses a set of phonograms in addition to and together with the logograms). Ultimately this means the Korean blocks are much more regular, since they're all composed from the same small repertoire of individual characters, with not even all that much complexity to kerning/ligature-like behavior, though font systems usually work with precomposed blocks instead of doing on the fly character composition anyway. Their shape complexity/stroke density is also lower. And handwriting recognition is massively simpler for all of those reasons.
