Encode / decode URLs
What's the recommended way to encode/decode URLs in Go? I am looking to the equivalent of encodeURIComponent in JavaScript.

In JavaScript, PHP, and ASP there are functions that can be used to URL encode a string. PHP has the rawurlencode() function, and ASP has the Server. URLEncode() function. In JavaScript you can use the encodeURIComponent() function.
Why do we need to encode? URLs can only have certain characters from the standard 128 character ASCII set. Reserved characters that do not belong to this set must be encoded. This means that we need to encode these characters when passing into a URL.
Double URI-encoding is a special type of double encoding in which data is URI-encoded twice in a row. It has been used to bypass authorization schemes and security filters against code injection, directory traversal, Cross-site scripting (XSS) and SQL injection.
If a URL contains characters outside the ASCII set, the URL has to be converted. URL encoding converts non-ASCII characters into a format that can be transmitted over the Internet. URL encoding replaces non-ASCII characters with a "%" followed by hexadecimal digits. URLs cannot contain spaces.
You're looking for the "net/url" package.
