[XeTeX] Long i with overbar and no dot

[Nathan Camillo Sidoli]

Hello All,

Is there a good way to get a long i with an overbar and no dot that can 
be changed by the environment to agree with the text that it belongs to.

I am using \={\i} at the moment, but this seems to call in a special 
character which cannot be modified. That is, it cannot be bold, italic, 
or enlarged for a heading, etc.

Below is a minimal file. It doesn't seem to matter what roman font I use.

Thanks,

Nathan
