You're right that Japanese routinely combines Kanji and the two kana. I believe that Korean often combines Hangul and Han. This is very well trodden ground. If you look at the IANA IDN practices tables, you can see the combinations that registries allow you to make. https://www.iana.org/domains/idn-tables R's, John
