So basically the font provided with EsoKR has the character 가 at 6E00 which falls in the range of the subset of Chinese Idographs. The character is actually referenced as AC00. I post the details in the issue on GitHub.
I have reported the issue to ZOS but that doesn't mean they need to fix anything or can fix anything. Basically there is nothing I can do at the moment.
