I suggested to Vignesh off the mailing list to apply the following patch:
http://pastebin.com/e3tJRYMP
i.e just adding:
glyphString[slen++] = C_DOTTED_CIRCLE;
+ item->attributes[slen-1].dontPrint = true; // FIXME this
will hide all dotted circle
However he found that this causes a crash. I wasn't sure of the correct
fix for this.
