I have a string that needs to be transformed into HTML format.

非常抱歉，{{coachname}}无法再在**{{sessiondate}}**的**{{sessiontime}} {{sessiontimezone}}**进行您即将参加的教练谈话。

非常抱歉，{{coachname}}无法再在**{{sessiondate}}<strong>的</strong>{{sessiontime}} {{sessiontimezone}}**进行您即将参加的教练谈话。

See babelmark here and you can verify that all CommonMark implementations behave the same here.

It is normal that you will get lots of error when converting from markdown - the result of the legacy Markdown package to CommonMark, but it will be unlikely an issue with Markdig, but more something that you will have to change in these templates to comply with CommonMark.
