What's in a Name?

While rooting around in the Autodesk Civil 3D 2005 Help system, I ran across the following:

Object and style names restrict the use of certain characters.

When naming an object or style, do not use the following characters:

< (less than)
> (greater than)
/ (forward slash)
\ (backward slash)
+ (plus sign)
“ (double quotes)
: (colon)
; (semi colon)
= (equals)
| (pipe)
, (comma)
* (asterisk)
? (question mark)
‘ (single quote)

It seemed obvious. But one should never assume.
