I just referrred to that way as a short-hand way of describing it's 
appearance instead of the code used to select it. 

In all the software I've ever used, and on findu, and in the updated 
symbol sets I have distributed up to the current "Rev H" that are 
derived from the US customary symbol set originated by K4HG,  the 
primary set "ampersand code" yields a black diamond (i.e. square rotated 
45 degrees) with a yellow letter "G" on it -- not as an overlay code but 
part of the base artwork of the symbol. 

I don't think anyone is using a secondary code plus overlay character to 
do this for an HF gateway.   At least, none that I have seen.  Indeed I 
have seen the opposite a number of times on VHF in my travels.  People 
are using the primary  /& "diamond-G"  symbol to identify a two-meter igate.

Anything that depends on overlaid symbols from the secondary set will 
simply not show on many users displays since many of the clients just 
don't support the secondary overlay technique at all,  or have 
out-of-date/incomplete symbol sets, or both.
