The org-mode syntax document describes entities as:
> \NAME POST
> \NAME{}
> Where NAME and POST are not separated by a whitespace character.and POST is defined as: > Either the end of line or a non-alphabetic character. So using the test document: ``` \_ Foo ``` (a backslash, underscore, three spaces, and then the word Foo) I would expect to get only 2 en-spaces but I am getting 3. Looking at org-entities, an underscore with 2 spaces gets 2 en-spaces, whereas an underscore with 3 spaces gets 3 en-spaces, but if we match all 3 spaces as NAME then POST becomes invalid because "F" is neither the end of the line nor a non-alphabetic character, so we can only match the first two spaces as NAME. emacs version: 29.1 org-mode version: 9bbc21df84d507e568a3ebd17e105cdb9e163784 (latest in git) -- Tom Alexander pgp: https://fizz.buzz/pgp.asc
