I've seen a problem with searching in the Prayer webmail client that turns out to be caused by Prayer insisting on a charset called "ISO-8859-1" and Dovecot, using Solaris iconv, not recognising it (all the Solaris 8 iconv modules appear to be "ISO8859-1" etc. or just "8859-1"). This isn't a problem in Linux: % iconv --list | grep 8859.1/ 8859_1// ISO-8859-1// ISO8859-1// ISO885911// ISO_8859-1// I've hacked together a patch for Dovecot to try matching without the "ISO-" prefix if matching fails at first, which works for Solaris (as would creating an extra symbolic link in /usr/lib/iconv or hacking Prayer to use "ISO8859-1") and it doesn't break Linux, but it's not pretty :( Better may be to try substituting underscores, hyphens, spaces(?) and nothing in the string, but that makes the change much more complicated!
