Does anyone know how to insert the direct current symbol (⎓) in Adobe Illustrator please? I copy and paste the character into a text frame but it becomes a cross square which cannot be displayed correctly. I switched to a number of different font types but no luck. I also tried to insert a symbol from Adobe Illustrator but cannot find any. Thank you very much!

As it's a technical symbol, you should look for a font containing such symbols, as Cambria Math font.

If copy/paste doesn't help, use the Glyph Panel to look for it: with the insert text cursor active, click twice the symbol at the Glyph panel.

Another option — without using a special font file — is to actually draw the symbol from 4 basic rectangles, group these, and copy paste where needed.
