What do most librarians use these day for the plus sign on Polarized Capacitors? 

Is text good to use? 

We use graphics, but am wondering about switching to text.

This question is for assembly shops and EE engineers. They have to deal with the silkscreen Legend that you provide them. 

Personally, I like the graphic symbol plus "+" as it clearly defines the polarity for Polarized Capacitors.

Polarized capacitors have large leakage current if the voltage is inverted. 

Not all the capacitors are polarized, but when they are, it’s very important not to mix their polarity up. 

Polarity indicates whether a circuit component is symmetric or not.
