> Hi,
> we came across the problem that the monospace font dejaVuSansMono has
> problems with spaces in strings if they are rendered in a pdf and a
> PDFType0Font is used for subsetting. If a space is placed within the strings
> the letters from every word are placed overlapping each other, see attached
> files. Seems that the advancedWidth array int the HorizontalMetricsTable
> contains a wrong, very low value as 3rd entry after subsetting the font. We
> compared it with a second monospace font, and it worked there. The difference
> between the two fonts is that the dejaVu Mono only contains 4 advanceWidth
> entries and the second one contains an entry for every glyph. This second
> font was VeraMono.ttf . The fonts are loaded via PDType0Font.load(doc,
> fontfile).
