This is not a bug, but an unfortunate (and arguably bad) design choice made by CommonMark. (See the [spec](https://spec.commonmark.org/0.29/#emphasis-and-strong-emphasis).) **tldr**: use `스크립트(script)라고` or, if you really want to use Markdown...

Although this PR works for Japanese and Chinese text (please note that Korean text uses "Western" punctuation marks), it does not solve a related but slightly different issue in Korean...

It seems that the issue on emphasizing Korean texts has not been reported before. I posted this issue in as a comment.

`fontTools.ttLib` cannot parse the `cmap` table as well. Interestingly, `fontTools` has no problem in parsing the TC version of the font, although these fonts are released on the same day.
