Hi!

I am trying to post a question that is quite long but I get an error message everytime:

"Please use only the following characters in your post: A-Z, a-z, 0-9, punctuation and basic symbols from the printable ASCII character set."

I cannot see any problems with the text.

My first suggestions is not to post a long question. People volunteer to answer questions and that takes time-- time that is in short supply. Long questions take a long time to read, think about, and formulate a response. You are less likely to get an answer if you ask such a question. Keep questions short and to the point.
