I don't know why some hacked-up CMS did not liked current iconv. But in phpinfo, iconv version shown as "unknown" which is probably traced to absense of /include/gnu/libc-version.h and I suspect that they check it or use some nonstandard extensions or PHP is mad. Building PHP 5.4 statically with gnu libiconv.a reset version to known one and everything works. I need to ask our php hackers about this (they maintain stuff) or grep for all iconv which appears in sources. > > > Musl much more perfect than I > > expected) > > Great to hear. :-) I replaced gnu libc stack with musl one on our middly loaded sites in large LAN/MAN and it works great and easier to maintain, fix and modify in a way you want :) > > Rich
