HTML Encoding in Drupal Entity References

Double Encoding Issue

Building complex websites with Drupal will undoubtedly require you to use the Entity Reference module. Overall, this is a great module with a lot of power and flexibility. It does have one fault, however, and that is that Entity titles are double-encoded when being shown in select boxes, as you can see here. This is nothing more than a small annoyance for experienced users, but show this to a customer and they will swear that something is broken!

As it turns out, this is a known problem, and at the time of this writing no general solution has been developed, due to issues beyond the scope of this short blog post. I'm just going to tell you how to fix it for yourself! All that is needed is a simple hook_form_alter() that will cycle through the options and remove the extra encoding, as demonstrated here in our ficticious misc module.
