yes, I still have that previous version in /var/cache/apt/archives, and
trying to install it with dpkg also fails with the same error.

yes.

$ php -r 'if (!function_exists("utf8_encode")) { die("no such
function\n"); }'
no such function
$

but:

$ php --version
PHP 7.0.14-2 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.14-2, Copyright (c) 1999-2016, by Zend
Technologies
$

and:

$ php5 -r 'if (!function_exists("utf8_encode")) { die("no such
function\n"); }'
$

(no output)

roundcube-core depends on php5, so it seems the php version 7 from
testing is to blame.  Indeed:

# update-alternatives --set php /usr/bin/php5
update-alternatives: using /usr/bin/php5 to provide /usr/bin/php (php)
in manual mode
# aptitude safe-upgrade
