I have just made this wiki page: https://wiki.debian.org/Punctuation
There are probably a lot of things missing. If you know about some corner of Debian tooling which has exciting syntax, please add the information you have. I have deliberately not listed use in regexps, because regexp engines have a quoting mechanism, and because I didn't want this to become a table of regexp syntax. I'm interested in things which appear in conventional filenames, RFC822-syntax metadata (in source and binary packages, etc.), apt and dpkg command lines, etc. It would be nice if the statement at the bottom Other than as noted above, punctuation characters are not permitted in package names and version numbers. could be extended to architectures, suites and filenames. Since architectures, suites and filename extensions are pretty much closed sets, it would be best if those responsible for assigning them documented what their actual rule is (which might differ from that documented in some code somewhere).
