Having launched Emacs with `emacs -Q -fn Inconsolata-12` I get

  [[0 0 59 541 29 2 7 9 4 nil]]

> It would be also interesting to compare this with a font that is

With `emacs -Q -fn "DejaVu Sans Mono-12"` (which displays correctly)
the output is

  [[0 0 59 30 11 3 8 10 3 nil]]

I've run both test on a scratch buffer showing its message, so they
should be referring to the character ";". `(font-get-glyphs (font-at
1) 100 101)` returns

  [[0 0 116 415 29 0 10 12 0 nil]]

with Inconsolata and

  [[0 0 116 87 11 0 11 14 0 nil]]

with DejaVu.

The fourth values look rather off, and the fifth too.
