(defun racket-unicode-input-method-enable ()
"Set input method to `racket-unicode`.
The `racket-unicode` input method lets you easily type various
Unicode symbols that might be useful when writing Racket
code.
To automatically enable the `racket-unicode` input method in
`racket-mode` buffers use `M-x customize-variable <RET>
racket-mode-hook` or put the following code in your Emacs init
file:
(add-hook 'racket-mode-hook #'racket-unicode-input-method-enable)
Likewise for `racket-repl-mode` buffers:
(add-hook 'racket-repl-mode-hook #'racket-unicode-input-method-enable)
To temporarily enable this input method for a single buffer you
can use `M-x racket-unicode-input-method-enable`.
Use `C-\\` to toggle the input method.
When the `racket-unicode` input method is active, you can for
example type `All` and it is immediately replaced with `∀`. A few
other examples:
omega ω
x_1 x₁
x^1 x¹
|A| 𝔸
test-->>E test-->>∃ (racket/redex)
To see a table of all key sequences use `M-x
describe-input-method <RET> racket-unicode`.
If you don’t like the highlighting of partially matching tokens you
can turn it off by setting `input-method-highlight-flag' to nil via
`M-x customize-variable`."
