Re: my Bidi implementation

[Behdad Esfahbod <behdad at cs dot toronto dot edu>]

Well, I read the whole code as soon as it was posted on the list.
First, there is a huge problem with bidi types, that are only
handled for ASCII/Latin1 and Arabic blocks, why?  Other than
that, well, the code pretty simply implements the bidi algorithm,
ignoring the details and hard parts ;).  But it's a good starting
point if you try the tests on it.

About tests, there are a bunch of them in the FriBidi source
code, with expected output, but aware that the CapRTL charset is
an invented character set solely for testing purposes...
