Yes, I found that one after I posted. FWIW, here are the changes for
the latest version:

That implementation looks very different from the C and Java versions.
I can’t tell by looking at a glance if it has been updated for the
changes in Unicode 8.0. But it definitely will not pass the tests in
BidiCharacter.txt because it lacks support for paired brackets.

I just finished writing a reference implementation in Lua[1] which is
a line by line port of the Java reference implementation and passes
nearly all tests in BidiCharacter.txt.

I now need to make the updates to support the changes in Unicode 8.0,
and I am finding it a bit hard to grok the changes in C at a glance.

Unicode Bidi Algorithm – Java reference implementation

[Deepak Jois]

Hi

It seems that the Java reference implementation for the Unicode Bidi
algorithm that I downloaded from the unicode.org site fails against
some test cases in the BidiCharacterTest.txt file – the ones that are
specifically meant to test for changes in Unicode 8.0.

Has the reference implementation been updated, and does anyone have a
copy they can share? Is there a reference implementation in some other
language that I could look at, which has been updated?

Thank you
Deepak
