surrogate-pair

Replaces the hexadecimal string under the cursor with the unicode surrogate pair.

Usage

Load the function with M-x load-file and then provide the surrogate-pair.el source code to Emacs to load it.

Move the cursor over the hex code (like in the section below) and type M-x surrogate-pair to call that function.

This should replace the code with the surrogate pair codes.

Test cases

1D552 (𝕒)

\uD835\uDD52 (𝕒)

Acknowledgements

I used this example by Xah Lee as a starting point:

http://ergoemacs.org/emacs/elisp_converting_hex_decimal.html

The idea for this helper came when I had to calculate a lot of surrogate pairs, first using the online calculator by Russell Cottrell from

http://www.russellcottrell.com/greek/utilities/SurrogatePairCalculator.htm

and later the information provided there to implement it.

So long, and thanks for all the fish

I moved this project to GitLab.

Kudos to GitHub for their ground-breaking work.
