Rosetta Code:Village Pump/Adding special chars

From Rosetta Code

I just added a new page for Raku (Perl 6) in the AV Tree task page. Raku allows apostrophes in identifiers so I used them to show off that feature. However, it seems to break highlighting so the text looks a bit funny with mixed colors.

I tried escaping the apostrophes with a backslash and with an html entity, but neither work. Then I realized the text in the <layout></layout> section probably needs to be valid code, so I changed back to valid code
