[TxMt] Display pretty symbols in place of ASCII

[Jonathan Middleton]

Hi, I'm fairly new to TextMate but I've been through the mailing list  
archives and was unable to determine if the following is possible.

In general, I'd like TextMate to display a unicode character in place  
of a sequence of ASCII characters. For instance, I'd like to be able  
to type => but have the editor display  ⇒  (U+21D2).

The saved file will need to be ASCII so I'm not looking for a way to  
replace characters, just a way to choose a different representation.

Is there a simple way to do this?

Thanks,
Jonathan
