Both triple ` and ~ should be supported as the start and end of fenced code blocks but only backticks seem to work here.
```plaintext
This is a fenced code block

I’m only familiar with US keyboards, they have both backtick and tilde keys.
But I understand some keyboards (European) don’t have bactick keys.
Would those keyboards have tilde keys?

That is not part of Markdown or CommonMark as far as I know.

[CommonMark Spec](http://spec.commonmark.org/0.19/#fenced-code-blocks). PHP Markdown Extra, kramdown and GitHub markdown support it.

Maybe unique to SourceForge flavor Markdown?

Oh my bad, if it is in the CommonMark spec we will support it for the official release of the CommonMark spec, once we have time to integrate. There is no official final release yet. Probably will take at least 8 months for all of that to happen, if not more.
