I a web page contains the null character (ascii 0), view selection source sees
this character as the end of string sentinel.  Therefore the popup menu item
"View Selection Source" doesn't appear if this character is the first selected
character.  Using � is equally good (bad).

I understand that this is an inherent problem with C strings.  I would appear
that other functions relating to the current selection may also be affected, for
instance the Web Search for "..." function also truncates the string.

In addition to the context menu, the actual source window displayed cuts the
character out, along with some of the surrounding text.  I get "null
characcode>'" when it should be "null character <code>'?'</code>".  (The full
view source window is correct - it displays a box character where the question
mark is).  

Reproducible: Always

Steps to Reproduce:
1. Create a web page with a null character (ascii 0) in the text.
2. Select text starting with the null character (it should be displayed as a box
character).  Select any amount of text as long as the null character is the first.
3. Right click to open the context menu and observe that no context menu items
relating to selected text appear.
4. Select some text including the null character as any character (aside from
the first).
5. Right click to open the context menu and observe that the 'Web search for
"..."' menu item truncates the text at the null character.

Actual Results:  
The null character appears to be acting as the end of string sentinel and
causing the context menu to display the wrong information.

Expected Results:  
The null character should could as a character in this aspect.
