autosize height if no spaces in text

PowerBuilder 11.5.1

we have a datawindow containing a text field, taborder is 0, autosize height is on

if the text field contains text without spaces, then the text is not wrapped at the end of the field and no autosizing happens...

anybody knows what we can do to show up the whole text spanned over more than one line even if the text contains no spaces?

Thanks Andreas
