I need to type the form feed character 0x0C in ASCII on my Mac. Is there any way to do this? I've tried using "Emoji and Symbols" from the Edit menu, but it's not in there.
It's there for me in Character Viewer (Emoji & Symbols, expanded version). It doesn't have a glyph, but if you double click it should be inserted. (Sometimes you may need to drag and drop to add.)
Note that you may have to go to the gear wheel at top left and select Customize to add the Unicode category. The Unicode category is under Code Tables.
