php 5.6.30 intl

Hello. PHP 5.6.30 with intl extension needs ICU. FreeBSD port has ICU compilled '--with-data-packaging=archive' option - intl extension accept this durning compillation. In mine environment php works as fpm with chroot, like /home/username/domainname.tld/ where is public_html as documentroot for webserver. Inside chroot is also roundcube webmail. Roundcube uses idn_to_ascii() function to determine $username and $domain_part - but idn_to_ascii() don't work, eg. idn_to_ascii($username) is empty, idn_to_ascii($domain_part) also is empty without any info/error/message. From roundcube team: "Looks like a PHP level issue. From intl extension we use idn_to_ascii() function. I guess it returns empty string instead of a properly converted string or sth." -- dsk
