We don't have mbstring installed (have ordered it at our server). using 
mb_substr() should solve the problem, but afaik the problem started 
after the upgrade to 4.2 (we did not update php at this moment, perhaps 
a security update was installed).

Only the caching is affected. The uncached preview is working fine (only 
the "ä" for example is cut to an "?").

We are currently using PHP 5.2.5 with Apache 2
