Hi Hans,
These commands are good to know!

\narrownobreakspace
If a font does not have U+202F defined, what's the best way to redefine
this to, say, one half of the current font's regular space U+0020 (with
no shrinking or stretching of course).
it has nothing to do with fonts ... they are not characters bound to  
glyphs .. independent so to say ... dealt with at another level
In spac-chr.mkiv there is

Line 73: \edef\narrownobreakspace      {\normalUchar"202F}

So in the preamble we have to do something like (spac-hor.mkiv, line 905)

\edef\narrownobreakspace{\penalty\plustenthousand\kern .7ex}

Then I can say, e.g.

\defineactivecharater + {\narrownobreakspace}

و+الباب

(untested, but on my list)

But per the current definition I should be able to define U+"202F as,  
e.g., .7ex in the font and get the same effect, right?

Best wishes
Idris
