I can't understand why this cannot be parsed, there are no spaces, and I'm not sure if it's in Chinese?

This is the relevant section of the commonmark spec: https://spec.commonmark.org/0.30/#emphasis-and-strong-emphasis

A right-flanking delimiter run is a delimiter run that is (1) not preceded by Unicode whitespace, and either (2a) not preceded by a Unicode punctuation character, or (2b) preceded by a Unicode punctuation character and followed by Unicode whitespace or a Unicode punctuation character. For purposes of this definition, the beginning and the end of the line count as Unicode whitespace.

It's essentially saying that the closing ** (right-flanking) have some rules around what characters can be present just before and just after it.

In your case, you have a 。 ("ideographic full stop") character right before the **.
This character is a punctuation character, so if you want the ** to be considered, it must also be followed by a whitespace or punctuation.

If you insert a space right after **, you should see it working again.
