Hi Hans,

thanks for the help. I had to enclose the symbol definition part in 
curly brackets:

\definesymbol[whatever][{\dontleavehmode\rotate[rotation=180]{\getglyph{ZapfDingbats}{234}}}]

Now the symbol is rotated without causing a new line. Yet, the rotated 
symbol appears below the current line:

text     text -> text
      <-

Is there a possibility to specifiy the center of rotation?

Thanks again,
--Stefan
