Hello aaronq227,
I see, some crap happened. I used the official governmental road sheet as a primary entry point where they're marked like "შ-123" (not the latest version - https://www.matsne.gov.ge/ka/document/download/5524325/0/1), but on road signs, refs are shown like "შ 123". I'll revise my changes later based on how it's shown on signs.
