问题
I was having a problem with meta attributes being double escaped in Grails, so for instance:<meta name="title" content="${'bla bla "bla"'.encodeAsHTML()}" />
was becoming:<meta name="title" content="bla bla &quot;bla&quot;">
Obviously removing encodeAsHTML() stops the double escape but it is strange as nothing else auto escaped, and not I'm sure where else things might be automatically escaped.
回答1:
It turns out meta, title and body tag's attributes have .encodeAsHTML() called on them within SiteMeshTagLib.groovy.
This should really be documented somewhere, because I couldn't find any mention of it and thought it might be a bug.
