Display direction of a line with truetype fonts?

[Wolfgang Qual]

Hi list,
I would like to display directions of lines using the mapserver. My idea 
was to create a suitable Truetype-Font (e.g. "A" for -->)
I added the font to my fonts.list and created an entry for my symbolfile.
However, when I look on the result, I see that the direction of the 
arrows does not match with the direction of digitizing (see this link [1])

Any ideas would be appreciated!

Best regards,

Wolfgang
