Not exactly... it wraps a style with the no-break feature on the space between those words. Similar to this:

HTML:

<p>Example…: final<span class="nobreak"> </span>words.</p>

CSS:

.nobreak {white-space: nowrap;}

But that's an InDesign feature using GREP. There are some queries around, but they're missing I-dont-remember-what because I edited years ago and I use it over and over. So I'm sharing it for the first time.

Oh, yes, the adobe paragraph composer algorithm is quite good.

Thanks for the info.

Well... InDesign uses GREP, but I think its too limited. Sometimes I have to copy the text and place it into Sigil to use its RegEx engine in order to find some things. I don't know if there's a better software for this, never looked into it, but Sigil works for this.
