Comment(by mail_ben_schmidt@…):

 I have updated the patch to address the autoconf version and variant
 issues.

 A better way of testing for the ICU library might still be nice. I found
 this which may help: http://ac-archive.sourceforge.net/ac-
 archive/ac_check_icu.html

 I'm also not 100% sure the patch is only effective for Unicode and doesn't
 mess up other multi-byte encodings. Still, now it's a variant, if it does
 mess something up, users can just turn it off. I did make the variant the
 default, though, as I expect most users will just be pleased that Unicode
 works as advertised. People might not even realise the issue has been
 addressed if the only change is a quietly added variant. Better to
 'advertise' the new functionality by making it the default; if it breaks
 for some people, they'll soon find the problem and disable the variant.
 IMHO.

 Not sure how likely this is to get merged upstream on account of this
 discussion: http://archives.postgresql.org/pgsql-
 general/2010-01/msg00535.php but I'm still hopeful.
