Wide body captain experienced a taxiway excursion while attempting to turn from taxiway right to tax...

Narrative:

When exiting runway 36R in clt airport; on romeo exit when turning left onto charlie taxiway (about a 135 degree left turn) at walking speed it felt like the left main brakes were dragging. Not wanting to hurt or damage the aircraft we stopped and called maintenance. When he plugged in he said the left main gear was slightly off the taxiway and on the frozen mud and to use enough power to power onto taxiway charlie. I applied enough power and the aircraft taxied onto the taxiway with no problems or damage to the aircraft. No taxi lights were run over.what would I do different next time so this does not happen again? If I exited onto romeo I would turn left on alfa (45 degree turn) left on gulf (90 degree turn) right on charlie (90 degree turn) instead of a 135 degree left turn onto charlie or I would exit 36R at C9 (90 degree turn) with a (90 degree turn) onto charlie. I have only been to clt one other time and I landed 18L with a right turn at C4. I think that [wide body aircraft] exiting on romeo should not try to make the 135 degree left turn onto charlie because there is no fillet. I also think this should be added to the 10-10 page.
