You can't. Although there are specific line breaks in unicode, there are 
also layout restrictions, for example: line wrapping. You really can't 
assume to know all the reasons to break lines from inside fribidi, it's 
something you only now in your layout engine. Unfortunately BiDi support 
is a pain and there are no real shortcuts.

I don't quite understand what you mean.


Have you considered using EFL ( www.enlightenment.org ) for your 
project? There's BiDi (and more) support there and the libraries are 
really thin and fast. Text is only a minor part there, they also provide 
whatever you may need to write an interactive application. They are used 
in various embedded projects, and by very big companies, including: 
Samsung and Intel (Disclaimer: I'm on the developers of the EFL).

If you are determined to use your own renedring framework, have you 
considered using pango? It should help you layout your text and will 
probably do what you want as well.

Both solutions provide a "simple" text_in -> text_out (not really, text 
out, but more like layout_out or bitmap_out) solution that may suite you.
