package require uri::urn ?1.1.2?
uri::urn::quote url
uri::urn::unquote url
_________________________________________________________________
DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with
the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to
handle urls using the urn scheme.
COMMANDS
uri::urn::quote url
This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its
result.

This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters,
and returns the modified urls as its result.
