Golang html.UnescapeString function example

package html

UnescapeString unescapes entities like "<" to become "<". It unescapes a larger range of entities than EscapeString escapes. For example, "á" unescapes to "á", as does "á" and "&xE1;". UnescapeString(EscapeString(s)) == s always holds, but the converse isn't always true.
