Usage: {{encode value}}
Description
{{encode}} is a simple output helper which will encode a given string so that it can be used in a URL.
The most obvious example of where this is useful is shown in Casper’s post.hbs, for outputting a twitter share link:
<a class="icon-twitter" href="https://twitter.com/share?text={{encode title}}&url={{url absolute='true'}}"
onclick="window.open(this.href, 'twitter-share', 'width=550,height=235');return false;">
<span class="hidden">Twitter</span>
</a>
Without using the {{encode}} helper on the post’s title, the spaces and other punctuation in the title will not be handled correctly.
