You need to install the PHP multibyte extension ("mbstring") as described here.

Search in your php.ini for this line:

;zend.multibyte = Off

And change it to:

zend.multibyte = On

Have you restarted your php-fpm-instance? – tjati Jan 12 '14 at 11:08
What operating system are you running? If Linux, which distribution? Are you using a package manager or have you compile php by your own? – tjati Jan 12 '14 at 11:13

Building on the answers from Phil Rykoff and omeinusch: this is my configure line to build php from source to support reportico 3.2 on php 5.4.43 / Centos 7.1.1503

/configure --with-apxs2=/opt2/canal/apache/bin/apxs --with-mysql
--with-pdo-mysql --prefix=/opt2/canal/php --enable-mbstring --with-gd

--enable-mbstring is pertinent to this question.
(--with-gd required from image handling (also needed yum install libpng-devel to avoid missing png.h message))

Then needed to set the following in php.ini:

zend.multibyte = On

If you're using cPanel hosting, you can go to PHP Selector and check the "mbstring" feature. It worked for me.
