Error with submitted multiline text

As I could see, there is a closed issue about multiline text #2 , but apparently this seems still to be a pending issue. Recently, I was trying to get a full list of all submitted data in a single CSV, but as my standalone solution is tailored to my form, it's not really usable here. But I can give a hint how I have solved it:

The multiline-textarea was the last field of my form. So, when I read the contents of the text data, I split the full content at the label value of the textarea

`$textarea = explode("\r\ntextmessage:",$fulltext,2);`

Then I manipulate all the linebreaks in $textarea[1] which now contains only the value of "textmessage". And then I just implode the array again by using the label value again:

`$fulltext = implode("\r\ntextmessage:",$textarea);`

Now I can handle the remaining linebreaks, as there is only one line per input/textarea.

This could be done globally, maybe referring to the original form values, but as I am not a developer, this seems too much for me to do in this place.
