Count Characters

The function returns the number of characters in a copied text, discarding desired one.

This function is of help if you want to count the characters of a text without considering some (e.g. special characters, citations, ...).
To use it, copy the text and just run the function.
If you want to exclude characters, you need to pass a regular expression (e.g. '( ){0,1}\[.*?\]' removes Zettlr inline citations) as argument (see https://it.mathworks.com/help/matlab/ref/regexp.html and use https://regex101.com/ to test your expressions).
