glyphIds in the set: \[0, 3, 36, 37]
number of metrics: 4
the current code increments {{hmetrics}} and adds {{3}} (number of metrics - 1)
to the set. The mistake is that 3 was already part of the set, so there was no
need to change anything. (3 is the last GID and its metrics are used for itself
and all bigger GIDs.

> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.2
> Reporter: Christian Maierhofer
> Attachments: DejaVuSansMono.ttf, TTFFontTestPDFBox2.java,
> VeraMono.ttf, doTest.pdf

> 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).
