Aha, got it. Sadly no, it's been a long time since I wrote C code...
I will check who the maintainer is of that plugin and see if he/she might be interested.
HTML chars is part of the Geany repository, so it doesn't have an individual maintainer, unlike those in the Geany-plugins collection.
You can make an issue requesting the feature on the Geany repo and see if you can interest "somebody".
