emoji in comment should not be processed

[upupming]

The following md:

So this: <!-- begin-inline-katex
\def\arraystretch{1.5}
   \begin{array}{c:c:c}
   a & b & c \\ \hline
   d & e & f \\
   \hdashline
   g & h & i
\end{array}
end-inline-katex-->

will be rendered as:

<p>So this: <!-- begin-inline-katex
\def\arraystretch{1.5}
   \begin{array}{c<img class="emoji" src="https://assets-cdn.github.com/images/icons/emoji/c.png" alt="c" />c}
   a & b & c \\ \hline
   d & e & f \\
   \hdashline
   g & h & i
\end{array}
end-inline-katex--></p>

It is expected to leave the content in comments unchanged.

Please use __colon__ instead of colon

So this: <!-- begin-inline-katex
\def\arraystretch{1.5}
   \begin{array}{c__colon__c__colon__c}
   a & b & c \\ \hline
   d & e & f \\
   \hdashline
   g & h & i
\end{array}
end-inline-katex-->

Hope it helps

is this __colon__ behavior documented anywhere? Does it work outside of code blocks? I'm running into a similar problem inside of a markdown heading:

For example:

## foo:bar:baz

which should render as

foo:bar:baz

but the colons are being used to try and load an emoji named bar.

@atuttle I tested normal, what's wrong with you?

[atuttle]

@sy-records I'm not saying that it doesn't work, I'm saying that it's undocumented. If this is the proper way to avoid unintentional conversion to emoji, it should be documented.
