Escaping the escape character

[shesek]

It seems like its currently not possible to write 'foo bar!' in bold, as **foo bar!** will cause the closing ** to be escaped by the !.

**foo bar!!** doesn't seem to work either - the second ! isn't escaped by the first one to be considered a plain !, but rather renders as: foo bar!**

Is there any other undocumented way to do that that I'm not aware of? If so, it should probably be mentioned in the WikiFormatting documentation. If no such way exists, maybe a double !! should be considered as a plain ! character, in the same way \\ works when the \ character is used for escaping?

Well, writing **...!!** is not significantly less intrusive than writing **...! **, which already works. Ideally this should be taken care of by the parser…

This is already on the list btw., in #3970. Please follow-up there if needed.

Well, it does cause an extra space. I noticed it in the description for #9638, right after the 'best invention since sliced bread!'… the extra space is what I eventually used, but it does look quite odd.

I noticed you added my suggestion to #3970… doubling the character is the approach taken in most places (PHP, SQL [either double \\ in some DBMS or double '' in others] and most places dealing with escape character), so I think its reasonable to use it.
