UTF-8 isn't? ..
No question, but now the function at least will try to respond somewhat to the error instead of nothing and just dying with 'highway-to-hell'-@.

This sanitizing method indeed needs a big refactoring on encoding detection and >>error handling<<

[DerDu]

i know its more like quick'n dirty but it only triggers if the value is not already UTF-8 and most of the time the error occurs in combination with öäü߀ not correctly encoded as UTF-8 so WINDOWS-1252 can handle this quite well (including mac)
