I wondered about this too, especially when I was tasked with deciphering foreign schematics.
IMHO, there should be two, and only two, schematic symbol representations for a capacitor: one symbol for a fixed capacitance and an identical symbol with an arrow through it for a variable capacitance. If that leaves it unclear exactly what type of capacitor is involved, refer to the Bill of Materials or text annotations on the schematic. Unfortunately, text annotations won't do much good if you cannot read the language... so consider the following:
This "symbol problem" will go away with the use of AI for "documentation." Years ago I was learning how to use a circuit analysis/simulation program that required me to enter the "schematic" in text form, listing components by "name" and the nodes to which that component was connected. An AI could instantly convert such a "schematic description" into a genuine schematic diagram using whatever symbols and/or annotations the user desired. Note that this allows duplicating schematics in ANY language, on line, no fuss at all: Just click on the filename, select a language of choice, and hit the "Enter" key. Voila! A fresh schematic, in your language, on-screen, using symbols popular where you happen to be instantly appears. Use it or download it to your favorite printer.
Since I am talking about using AI, why not allow the AI to "examine" an image of a printed schematic and then re-create that schematic as described in the previous paragraph, custom symbols and language of choice included?
