[icu-support] Collation in ICU 3.4 with ALTERNATE SHIFTED - strange results

[Scott M. <Sco...@sa...>]

Is there a problem with 3.4 and ALTERNATE SHIFTED?  I'm sorting with an =
en_US locale, a STRENGTH of 4, and ALTERNATE SHIFTED and I'm getting =
some strange results.  I'm sorting a list of three strings:

  2004
  2010
  23

and ICU 3.4 is returning the keys:

  25 7E 25 82 01 06 01 06 01 26 25 7A 25 7A 26 00
  25 7E 25 7C 01 06 01 06 01 26 25 7A 26 25 7A 00
  25 7E 25 80 01 06 01 06 01 27 00

respectively and this results in an order of:

  2010
  23
  2004

Without ALTERNATE SHIFTED, I get the following keys:

  25 7E 25 7A 25 7A 25 82 01 08 01 08 01 26 00
  25 7E 25 7A 25 7C 25 7A 01 08 01 08 01 26 00
  25 7E 25 80 01 06 01 06 01 24 00

and this results in the order:

  2004
  2010
  23

I checked against the demo page here:

  http://demo.icu-project.org/icu-bin/locexp?_=3Den_US&d_=3Den&x=3Dcol   =
                                  =20

with and without the additional custom rule [alternate shifted] but this =
is returning different keys, leading me to think that this demo page =
might be using 3.6.

Can anyone offer a quick sanity check here?  It would be much =
appreciated.
