Hi all.

I want to use some arrows of the ZapfDingbats fonts. Most of the 
arrows included in this font are directed from left to right. I tried 
to use \rotate to produce arrows directed to different directions. 
Yet, rotate produces new lines.

Example:

\definefontsynonym[ZapfDingbats][zd]
\definefont[Zapf][ZapfDingbats at 24pt]
\rotate[rotation=180]{\Zapf\char234} {\Zapf\char234}

The example is intended to produce an arrow directed to the left 
followed by an arrow directed to the right. The result however is an 
arrow directed to the left followed by a new line with an arrow 
directed to the right.

intended:
<- ->
result:
<-
->
Does someone know how the new line can be suppressed?


(untested)

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

\symbol[whatever]
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
