Raku programming language uses some unicode characters as operators, quotation marks, etc. In this post I'm going to explain how to type those characters in Emacs using input methods.
First, you might want to see a list of those characters and their ASCII equivalents here. There is also a doc for entering unicode characters. You may specifically want to look at XCompose for a system-wide solution.
There are at least two input methods you can use to enter the unicode characters used in Raku.
