";" would be a very bad character in my opinion -
"http://100.100.100.100;/bin/rm -rf /"
could cause a lot of problems in poorly written scripts that process
URLs. Shell characters should be avoided as much as possible, I think.
I could live with the use of "." to separate the port in IPv6 addresses,
though it does allow "http://::131.247.108.14.80/", that is not an
ambiguous representation.
