+
+Vim-raku provides syntax highlighting, indentation, and other support for
+editing Raku programs.
+
+1. Using Unicode in your Raku files	|raku-unicode|
+
+==============================================================================
+1. Using Unicode in your Raku files                           *raku-unicode*
+
+Defining new operators using Unicode symbols is a good way to make your
+Raku program easy to read. See:
+https://perl6advent.wordpress.com/2012/12/18/day-18-formulas-resistance-is-futile/
+
+While Raku does define ASCII alternatives for some common operators (see
+https://docs.raku.org/language/unicode_ascii), using the full range of
+Unicode operators is highly desirable. Your operating system provides input
+facilities, but using the features built in to Vim may be preferable.
+
+The natural way to produce these symbols in Vim is to use digraph shortcuts
+(:help |digraphs-use|). Many of them are defined; type `:digraphs` to get
+the list. A convenient way to read the list of digraphs is to save them in a
+file. From the shell: >
+        vim +'redir >/tmp/vim-digraphs-listing.txt' +digraphs +'redir END' +q
+
+Some of them are available with standard Vim digraphs:
+	<< «    /0 ∅    !< ≮  ~
+	>> »    Ob ∘    !> ≯  ~
+	., …    00 ∞    (C ⊂  ~
+	(U ∩    -: ÷    )C ⊃  ~
+	)U ∪    (_ ⊆    >= ≥  ~
+	?= ≅    )_ ⊇    =< ≤  ~
+	(- ∈    ?= ≅    != ≠  ~
+	-) ∋    ?- ≃  ~
+
+The Greek alphabet is available with '*' followed by a similar Latin symbol:
+	*p π  ~
+	*t τ  ~
+	*X ×  ~
+
+Numbers, subscripts and superscripts are available with 's' and 'S':
+	0s ₀    0S ⁰  ~
+	1s ₁    1S ¹  ~
+	2s ₂    9S ⁹  ~
+
+But some don´t come defined by default. Those are digraph definitions you can
+add in your ~/.vimrc file. >

+
+Alternatively, you can write Insert mode abbreviations that convert ASCII-
+based operators into their single-character Unicode equivalent. >
