Question

Field labels in Views are assuming plain-text input and they are probably using check_plain() to encode special characters (didn’t actually look at Views back-end).

How can HTML code be used inside labels?

Edit: I thought my question is clear. I don’t want to rewrite fields, I want to use HTML code inside a label, that’s all.

I figured it out. While you can’t use HTML input inside labels on the Views UI, you can customize a label inside a style output template.

e.g. for an “example” view that uses a table style output you would customize views-view-table--example.tpl.php and use a code like:

//custom label for title field
$header['title'] = '<strong>Foo</strong> bar';
