Some time ago, I've implemented an algorithm for DocBook. I wrote a
XSLT template that inserts zero-width space characters before or afters
specific characters.

Although the stylesheet is based on DocBook, I assume it can be easily
adapted to DITA as well:

The template covers some specific things, for example, it doesn't break
before "http://" strings. 

You need to define some parameters (ulink.hyphenate.before.chars and
ulink.hyphenate.after.chars) where you can find here:

Hope this gives you some inspirations. :)

Good luck!
