Travelling further in the wrong direction is always an option, but don't 
expect it to get you closer to the right destination.

Full text shaping is the only way to get this right. Everything else is 
a hack, and piling hacks on top of hacks is just storing maintenance 
problems up for yourself.

I know that's hard to hear for a volunteer project where nobody really 
wants to invest the effort in this complicated niche stuff, but 
honestly, you're probably better doing *nothing* than doing this.
