Check_MK Werk 2896: Improved handling of wrong encoded input strings

ID: 2896 Title: Improved handling of wrong encoded input strings Component: Multisite Level: 1 Class: Bug Fix Version: 1.2.7i4 When a user submitted non UTF-8 encoded strings, for example latin-1 encoded ones, where we expect to get a UTF-8 encoded string, this resulted in a cryptic exception. This has been fixed now by raising an understandable error message in most places.
