From a2c6355f9fdede78ce46aeee39ef649637aaadf9 Mon Sep 17 00:00:00 2001 From: Mark Lodato Date: Tue, 09 Feb 2010 15:12:43 +0000 Subject: html: properly percent-escape URLs The only valid characters for a URL are unreserved characters a-zA-Z0-9_-.~ and the reserved characters !*'();:@&=+$,/?%#[] , as per RFC 3986. Everything else must be escaped. Additionally, the # and ? always have special meaning, and the &, =, and + have special meaning in a query string, so they too must be escaped. To make this easier, a table of escapes is now used so that we do not have to call fmt() for each character; if the entry is 0, no escaping is needed.
