Default [Q] List of Signal Indicators

Can anyone tell me or point me in the direction of somewhere I can find a list of all the possible cell network signal indicators used by stock Android? Specifically, what I am looking for is what symbols can be shown next to the Cell Signal Strength Indicator in the notification area of android. I personnally can confirm I have see G, E, 3G and H and am guessing the full list is something similar to the following but am not able to get a definitive list:

G: GPRS
E: Edge
3G: UMTS
H: HSPA
H+: HSPA+
4G: LTE

I have searched the source code and found this but it just tells me what is classified as 2G, 3G and 4G, not what indicator symbol is used...
