[emacs-bidi] UTR#9 - Unicode BiDi (was Re: OpenOffice BiDi kudos) (fwd)

[Behdad Esfahbod]

Handa San,

Is it true that your implementation of Unicode Bidi algorithm
does not follow the UTR#9, with respect to handligh dash?  Just
wanted to make sure this is not true, otherwise, please consider
following the standard.

Thanks,
behdad,

This is a known issue with Unicode BiDi. It arises because we use the -
character for both minus and hyphen. When one wants to connects letters
with numbers one is using a HYPHEN and wants it to appear as 5-word.
When one wants to write a negative number one uses a MINUS SIGN and
would like it to appear as -5 word. The Unicode wise men have ignored
the 1st case (or require the use of a special Hebrew MAKAF). I have
pointed this and some other problem at the m17n2000 conference. (See
http://www.m17n.org/m17n2000_all_but_registration/proceedings/ehud/
See slide no. 10). I proposed my solution (slides 11-15) and this
algorithm was implemented by Kenichi Handa in his Emacs-BiDi (see
notes on http://www.m17n.org/emacs-bidi/ ).

Ehud.
