Hi Brando,
Good morning,
let me first say, that my transistion from 1.8 (svn) to 14.1 (rpm)
went surprisingly smooth, as when following the lists, one could get
the impression that there are many problems and caveats (which is
obiously NOT the case for at least my setup).
Nice to hear 
There is however one cosmetic issue I would like to address, before
14.2 hits the road:
asyncwrapper keeps sending me mails hourly with the following content:
PHP Deprecated: ini_set(): Use of mbstring.internal_encoding is deprecated in
/usr/share/egroupware/phpgwapi/inc/class.translation.inc.php on line 171
For the record: I’m on openSUSE 13.2 with PHP 5.6.1
I’m changed the mentioned line from
ini_set(‘mbstring.internal_encoding’,self::$system_charset);
to
ini_set(‘default_charset’,self::$system_charset);
which stops these mails.
I did not notice any regression in functionality with this change,
however, as I’m not an php-expert, I’m not sure if this is equivalent.
But in case it is, this minor change would mak emy inbox quite happy…
Fixed in Trunk / upcomming 14.2 with r49760:
http://svn.stylite.de/viewvc/egroupware?revision=49760&view=revision
Let me know if it works for you.
Anyway keep up the great work,
Thanks 
Ralf
