Hi, I encountered an interesting problem with pdf/a-1b checking: if a pdf (produced by pdftex) contains a glyph with zero width (for example, /mapsto from blsy/mtsy), then pdf/a-1b preflight by Acrobat8 gives warnings about incomplete/inconsistent width info. From the technical view, the pdf file seems to be ok: the glyph width in the fontinfo dict is 0 (read from mtsy.tfm), and from the font program: ,-------- | /mapsto { | 56 0 hsbw | ... `-------- So the reason seems that when Acrobat sees a zero glyph width, it treates that width as "missing". Does anyone have some similar experience with this? Thanh
