Hi,

Yes, you're right, the raster based text rendering capabilities are rather
limited, only a few set of predefinied glyps are selectable which cannot be
localized either. To define further characters you'll probably have to patch
something like agg_embedded_raster_fonts.cpp and define your own image
inside the code. But I don't think if it was a convenient way to do such
things locally.
However, I think you should be able to use the truetype fonts with agg to
display such fonts fairly well.

As far as I remember, there have been some efforts to take over some control
of the code in mapserver (at least for 2.4) and apply fixes if necessary,
but I'm not sure how do things stand in this topic at the moment.


Best regards.
