Heh - I'd actually forgotten about it until a couple of weeks ago when I
had to write some code to independently process the each soft-wrapped
line of styled text in a field.
I half wrote some code to do what I wanted in a different way while
wishing 'if only I had implemented the formatted variant for styledText
wayback when' - then I happily remembered that I had!
If you have a moment to file an report in the QC, we can get it added.

Hmmm - there's no code to do that explicitly (a semi-colon is no
different from any other char!). Non-merged style runs can occur through
some script operations on a field though (the engine uses 0 length runs
sometimes as markers - they would probably cause that effect). It could
also be due to the structure of the htmlText being imported
(potentially). If you have a simple example, then I can probably say one
way or the other.
The formattedStyledText, like the styledText, is just a array version of
the data-structure the engine holds inside (although it never emits 0
In this case that shouldn't matter though as it will be the text that
you want to count, not the runs.
