I run this command to search for symbols but it often does not have the symbol I require

vimhelp digraph-table

I had to Google for these symbols as they were not in the list

List of symbols we wish to make into digraphs ℕ - double-struck capital N ℤ - Zahlen - double-struck capital Z ℝ - double-struck capital R



Run the unicode program to find the decimal ID for each symbol we want

unicode ℕ unicode ℤ unicode ℝ

Add them to the vim digraph table

Vim uses the decimal value of the symbol.

This is the code to be added to vimrc

```vimrc digr ZZ 8484 digr NN 8469 digr RR 8477 ```

Add them to evil-mode for emacs

emacs uses the hex value.

The unicode command doesn’t provide the hex so we must convert them.

p 8484 | dec2bin

This is the code to add to your .emacs
