SSRS : Wingdings check box not displayed in Chrome and Firefox

I am trying to display the checkbox on the SSRS report based on the value of a Boolean field wingdings font. My expression looks like this.

=IIF(Fields!ColorCheck.Value,chr(254),chr(168))

This works fine in IE but not in Chrome or Firefox.

I tried the Unicode alternate for this (Arial Unicode MS Font) =iif(Fields!ColorCheck.Value,chr(0252),chr(0251))

I get the error "Procedure Call or Argument is not valid"

Is there any workaround for this. any suggestion is greatly appreciated.
