-

is possible display ⇓ entity in ie6? being display in every browser not ie 6.i writing markup such as: 

<span>&#8659;</span>

according this page, symbol doesn't show in ie6 @ all. 

symbol  character  numeric  description ⇓       &darr;     &#8659;  down double arrow - -  * doesn't show ms ie6

if need particular symbol, may have go small graphic of arrow - not ideal solution, if need display in ie6 may option.
