Add more tags if you need into $allowed_tags = ...

function _20170529_excerpt($text) {

You can add rich text editor for excerpts as well, add below code in plugin file or theme's function.php file and you'll be able to see HTML editor for excerpts. Moreover, it'll render excerpts in HTML format as well. #cheers

I've copied this from somewhere but don't remember the source. I'm using this in my all projects and it's working.
