My client, an advertising office, designs a magazine for on-line previewing based on PDF. Unfortunately, one single letter of the font is rendered with a strange shape around the letter. Accented letters A are affected (single A is fine). The letters look OK in InDesign as well as in Acrobat.
I did everything I could to avoid this problem: I changed direction of curves, I added a few redundant nodes, I did place the shape of Á to another glyph position. The Á is still rendered with the black shape.
Any idea what could be a source of this strange behaviour?
