== [ɡ̄] == 

 What consonant is [ɡ̄] meant to represent? As far as I can tell, this is not official IPA usage, unless it's meant to represent a voiced velar stop with a retracted tongue root - but wouldn't that just be a uvular [ɢ]?  

 If [ɡ̄] is meant to represent a geminate, standard IPA practice is doubling the consonant [ɡɡ] or (less commonly) adding the length diacritic [ɡː].
