Talk:URL encoding

I believe that some symbols are usually not encoded in URLs. The exact list varies, but they usually include the period (.) and hyphen (-), and sometimes underscore (_). Should we not include those? This is complicated by the fact that there are several standards on URI syntax (RFC 1738, RFC 3986), additional restrictions for specific protocols, like HTTP (e.g. the plus character (+) is encoded in form data), as well as lots of slightly different implementations across languages (and sometimes even in the same language). So whatever solutions that people present that use library functions will invariably encode a slightly smaller set of characters than in the task specification. It would be hard to keep all the solutions consistent. --98.210.210.193 07:06, 17 June 2011 (UTC)
