It serves more as a reminder of convert's way of specifying the
contents of the file than much else. Adding -font unicode also dredges
up the awful-looking ttf font. But given that the PDF produced is so
blurry, that font is probably no worse looking than any other.
The PDF is unsearchable because it's really just an image wrapped in
a PDF container (like the output from some scanners). Being an image,
there's no concept of wrapping long lines either.
I can't really be bothered to figure out what's missing on those
systems of mine that say:
$ convert -font unifont text:/etc/default/grub /tmp/grubby.pdf
convert: not authorized `/etc/default/grub' @ error/constitute.c/ReadImage/412.
convert: no images defined `/tmp/grubby.pdf' @ error/convert.c/ConvertImageCommand/3210.
