You could construct one from other glyphs in your darling font! (By  
using o, O, or 0 at one size and / or FRACTION SLASH ⁄, U+2044, or  
DIVISION SLASH ∕, U+2215, at another size at different height and  
some negative kerning between them.)

On Linux you could use, I think, GNUcharmap to check particular glyphs  
of the fonts you have. Once you've one, you can:

	\newfontfamily{\my_DIAMETER_font}{your font's name}
	\catcode"2205=\active
	\def⌀{{\ my_DIAMETER_font\char"2205}}

and then use in the text the symbol ⌀ and it will be set in that font.


BTW, some elderly LaTeX packages which handle special symbols, cannot  
be used (easily) in XeTeX because they use rather strange and non- 
Unicode fonts. Unicode encoded fonts are best suited for XeTeX.
