hello, currently we have the following markdown string: **C:\\**test\\

we would expect an output of C:\test\ unfortunatly we get the following **C:\**test\ , is there a reason why that is the case?

Yes, you can see that all CommonMark implementations behave the same here

That's expected as per CommonMark specs for 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 punctuation character, or (2b) preceded by a punctuation character and followed by Unicode whitespace or a punctuation character. For purposes of this definition, the beginning and the end of the line count as Unicode whitespace.

The case here in is that on the right of **C:\\** there is test which is not a whitespace or a punctuation.

so is there a way to additional escape the string to satisfy the requirement without adding whitespace?

Edit: or is the only way something like this:

ToHtml(...).Replace(" ", "");?

Nope, as per the spec, punctuation or whitespace.

You would have to change it like that **C:**\\test\\ or write directly HTML inlines C:\\test\\
