Raku uses Unicode chars like "»". Its hard to search for information on these chars as they don't seem to be searchable in Google and I don't really know their names. For example, something like the "»" in:
$/.make: $<pair>».made
Is there a descriptive list of all special Unicode chars used in Raku?
I think Unicode versus ASCII symbols section in Raku docs is what you're looking for.
Please note that you can search for » in the search box on the Raku documentation web site. It will give you an extensive pulldown on where » can occur in Raku.
You can use google doc to draw your character:
Insert -> Special characters, Draw a symbol here
