Comment (by hnle):

 With utf8mb4 on HHVM, texts are corrupt. All non-ASCII characters turns
 into "?" mark.


 == 　Problematic environment ==

 - OS: CentOS 6.6
 - Server: Nginx 1.6.2
 - HHVM: HHVM 3.2 (Unofficial:
 http://www.hop5.in/yum/el6/repoview/hhvm.html)
 - DB_CHARSET: utf8mb4
 - DB_COLLATE: utf8mb4_general_ci (and utf8mb4_unicode_ci)
 - WP: 4.2-alpha-31269 + 21212-utf8mb4.6.diff
 - MySQL: 5.5.41(Percona Release37)
 ​
 but… the problem is not happen on HHVM3.5.0 (or 3.2.0 too) + Ubuntu 14.04
 + MySQL 5.5.41.
