Will try and figure out the sequence.
In an ERE . matches any character. The intent is to match only a period at the start of those patterns. Change each occurrence of "\." in the script to "[.]" and it should get rid of the warnings and restrict the match to what was intended. (You could also use "\\.", but I find the matching list expression easier to use than trying to remember how many times a quoted expression will be evaluated by awk in cases like this.)

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 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. uri::urn::unquote url 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. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category uri of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].
