test program

Description of problem:
Perl does not recognize 'ӏ', the small letter Palochka (U+04cf).  This letter was added to Perl with UCD 5.0 support, but RHEL 5 Perl is still based on UCD 4.x.

http://perl5.git.perl.org/perl.git/commitdiff/98fbe98930ddfea1c62d93ddeb877f51263c4d25?hp=85c3142dc721254f0ad6b78e1d67d47cfdd317eb

Please update Perl to include UCD 5.0 or newer to support the small letter Palochka.


Version-Release number of selected component (if applicable):
perl-5.8.8-32.el5_5.1

How reproducible:
every time

Steps to Reproduce:
1. run the attached demo program:
      ./unichartest.pl
  
Actual results:
Small Palochka is a non-existent character:
    $ ./unichartest.pl 
    The codepoint of small Palochka is 1231 (0x4cf)
    Capital Palochka (Ӏ) is a letter.
    Small Palochka (ӏ) has the Other General Category property.
    Small Palochka (ӏ) is an unassigned or nonexistent character.

Expected results:
Small Palochka is recognized:
    $ ./unichartest.pl 
    The codepoint of small Palochka is 1231 (0x4cf)
    Capital Palochka (Ӏ) is a letter.
    Small Palochka (ӏ) is a letter.

Additional info:
There is a patch already in the perl source RPM, perl-5.8.8-bz204679.patch, however, it is not applied during build time because it breaks the build.

patch from CVS with fix of build failure

This patch was added into cvs by jvidias in 2006. I've add missing file into this uploaded patch, but there could be some still missing parts. Branch maint-5.8 should be investigated for latest changes related to this patch before fix.
