composition-function-table

["Yair Friedman (Jerusalem)" <YAIRFR@xxxxxxxxxx>]

Hi,

I'm trying to use composition for Hebrew with accents.  For that the
composition function has to be registered in composition-function-table.
However, this table doesn't appear to be documented. 

Looking at other languages it seems that the registration should be
something like:

(aset composition-function-table (make-char 'hebrew-iso8859-8)
   '(("\\c0\\c4\\|\\c0\\(\\c2\\|\\c3\\)\\c4?" . hebrew-composition-function)))

But that is th meaning of this regex?

Thanks a lot,
