User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

Using Lucida Grande on MacOS X, some Unicode glyphs display incorrectly. In particular, 0x21E6-0x21E9 appear as logical symbols rather than the arrows that they should be. 

MacOS X defines 0x21E7 as the glyph for representing the shift key. Firefox incorrectly renders 0x0005 as this arrow. This behavior is inconsistent with both the MacOS X system Character Palette and the behavior in Safari.

I was able to get the correct character glyphs using monospace instead of Lucida Grande though many other fonts behave like Lucida Grande.

Reproducible: Always

Steps to Reproduce:
<div style="font-family: 'Lucida Grande';">
  0x0005: &#x0005 (<span style="font-family:monospace;">&#x0005</span>)<br/>
  0x21E6: &#x21E6 (<span style="font-family:monospace;">&#x21E6</span>)<br/>
  0x21E7: &#x21E7 (<span style="font-family:monospace;">&#x21E7</span>)<br/>
  0x21E8: &#x21E8 (<span style="font-family:monospace;">&#x21E8</span>)<br/>
  0x21E9: &#x21E9 (<span style="font-family:monospace;">&#x21E9</span>)<br/>
</div>

Actual Results:  
Lucida Grande glyphs are incorrect and don't match the monospace glyphs.

Expected Results:  
Glyphs should render as blank/empty, left arrow, up arrow, right arrow, down arrow and match the monospace glyphs.

And unfortunately  is reported as an invalid character in an XHTML page so there is no work around in this case.
