Double Sharp in Latex

[Hugo Ribeiro]

Does anyone know how to insert a double sharp symbol into a latex code?

I just know those musical symbols:

$\sharp$ - $\flat$ - $\natural$

To insert a double flat I just need to write it twice as 
($\flat$$\flat$). But a double sharp is a different symbol, and I didn't 
find it anywhere...

Thanks,
