+### Question
+
+How can I use an entity like "nbsp"?
+
+### Answer
+
+If you try to do this:
+```clj
+[:div  "hello" "&nbsp;" "there"]     ;; <--- note: attempt to use an entity
+```
+then you will see the string for the entity. Which is not what you want. 
+
+Instead you should do this:
+
+  1. Require in goog's string module...
+
+  ```clj
+  (:require [goog.string :as gstring])
+  ```
+
+  2. Use it like this ... 
+
+  ```clj
+   [:div "hello"  (gstring/unescapeEntities "&nbsp;") "there"]
+  ```
+
+Note that `unescapeEntities` relies on the DOM to produce a string with unescape entities;
+in nodejs the DOM is unlikely to be available (unless you try using
+[`jsdom`](https://www.npmjs.com/package/jsdom-global)).
