Well, I don't really, but some searching turned up

http://indictrans.in/en/documentation/howto/yuditwindowshowto

Which suggests you have to copy a ttf (presumably with the relevant 
glyphs...) to the fonts directory under your yudit installation, rather 
than expecting it to pick up windows installed fonts,  and declare it 
ttf in the yudit.properties file.

There's also
http://www.yudit.org/en/howto/configure/
and question 8 in the FAQ looks relevant:
http://www.yudit.org/en/faq/

I don't really know yudit well, I just installed it via the debian 
package manager, it apparently looked after creating a proper 
yudit.properties file for me (attached, though obviously for debian).

N.B. I only looked at whole lines of R2L or L2R in it previously - note 
in the previous screenshot that any newlines in the yudit buffer are 
shown as visible blue "enter" glyphs, otherwise you can assume they're 
continuation lines. i.e. I didn't mean re-flow as in re-fill (inserting 
newline bytes into the file as necessary), I meant re-flow as in wrap 
into continuation lines. Possibly that was a bad use of re-flow on my 
part, I dunno.  (In context of the previous post in question, it was to 
point out that yudit doesn't _do_ truncation, only wrapping (and uses 
the window margins for wrap column), so the question of horizontal 
scrolling doesn't arise in it.)

I did not previously look at single lines of mixed R2L and L2R text 
being wrapped into continuation lines.   As far as I can tell, an L2R 
line will be continued at the left even if wrapped at an R2L span 
within it.  An R2L line will be continued at the right even if wrapping 
at a L2R span within it.

I've attached new screenshots, before and after resizing the window to 
cause wrapping, anyway.  yudit has word boundary wrapping, so there's 
two after shots, one with it on and one with it off (see FAQ Q18). 
They're probably not all that helpful compared to having a working
yudit to play with though.
