I did this:
$ apt-cache pkgnames | tr -d 'a-zA-Z0-9' | tr -d - | tr -d '\n'

The only remaining characters were '.' and '+'.

I did:

ls -1 /var/cache/apt/archive/ | tr -d 'a-zA-Z0-9' | tr -d - | tr -d '\n'

Got:  . + % ~ _

typical pkgnames, as seen in the file system:
zlib1g-dev_1%3a1.2.8.dfsg-2ubuntu4_amd64.deb
zoo_2.10-27_amd64.deb
zynjacku_6-4build1_amd64.deb

Note pkgname:

package-name  _  upstreamversion - localversion _ otherstuff

version delimited by _

may have optional subversions split by -
(like when an upstream version is remade on hydra, but is only locally different somehow.)

For your comtemplation.

I believe on debian the : is used when the package starts a new numbering scheme, like when

they decide the old scheme was crazy.
