Hi Clemens,
thanks for your answer, but I think that your code does not help to solve
the problem. I just ran some more tests and if the 'content' variable only
contains ASCII characters (tried 'Data without german umlauts.'), the
problem happens all the same. IMHO it is not a problem with non ASCII
characters and therefore not solved by escaping them by any means.
Maybe I had the wrong focus while writing the post.
Kind regards,
Silvan
