All many thanks.

The problem was really solved by copying/usr/lib64/gconv in /chroot. Why mbstring didn't work and whether it works now - I don't know, but iconv, obviously, works.

Vladimir,

Is it possible to add iconv to your chroot? Are you permitted to since this is a production machine?  If so that seems your best option.  It seems as though you will need to copy the /usr/lib/gconv directory into your chroot root as well.

See https://bugs.php.net/bug.php?id=44096 towards the end if the page.
