Less Than '<' and Greater Than '>' not allowed in Courier New Monospace

[Gregg Current]

Steps to reproduce

1. Enter text "Click <Finish>."
2. Highlight the text "<OK>" and set the font to Courier New
3. Save the text.
4. Reload the text. (I am using CKEditor in a database application so the text is stored in a record for redisplay)

Expected result

"Click" and "." will be displayed in the default (Ariel?) and the "<OK>" will be displayed in Courier New

Actual result

Click . in default font

Other details (browser, OS, CKEditor version, installed plugins)

CKEditor 4.5.2 Full version Browser Safari 7.1.7

This also happens when I save the marked up text to an HTML file and try to display the page. <p>Click &lt;<span style=&quot;font-family:courier new,courier,monospace&quot;>OK&gt;</span>.</p> Displays the Click < in default font OK in Courier New and >. in default font

<p>Click <span style=&quot;font-family:courier new,courier,monospace&quot;>&lt;OK&gt;&nbsp;</span>.</p> Displays Click . in default font

This is a source that CKEditor sends to the server (you can check it by switching to the source mode):

<p>Click <span style="font-family:courier new,courier,monospace">&lt;Finish&gt;</span>.</p>

This content is correct, so it is your backend what breaks it or the data is incorrectly loaded to CKEditor (remember to encode HTML entities before loading a raw content into a textarea).
