I made this neat font because I was annoyed by the lack of good notations!

Guide:
(a, b) Wire corners [south-east, north-west]
(c) Capacitor
(d) Varicap
(e, f) Polarized Capacitor [down, up]
(g, h) 3-Way intersection [up&right&down, down&left&up]
(i, j, k) Inductor [start, middle, end]
(l, m) AC Source [*down, *up]
(n, o) Diode [down, up]
(p, q) DC Source [down, up]
(r) Resistor
(s) Varistor
(t, u, v, w) Transistor [-up, -down, +up, +down]
(x) Light emission
(y, z) Ground [left, right]
(1, 2, 3, 4, 5, 6, 7, 8, 9, 0) Values {no rotation, see ~}
(!, @, #, $, %, ^, &, *, (, )) Ordinals [f, p, n, μ, m, K, M, G, T, P] {no rotation, see ~}
(_) Wire {uppercase is -}
(=) Crossing {no rotation}
(+) 4-Way Intersect {no rotation}
(\, /) Switch [0, 1] {uppercases are | and ?}
(') Antenna {no rotation}
([, ], {, }, :, ;) Units [F, Ω, V, A, H, z] {z included for hertz, no rotation, see ~}
(~) Anti-Space {Used for values and ordinals and units to overlap, no rotation}
(`) Space {Used to separate values and ordinals and units, no rotation}

UNUSED:
(", >, ., <, ,) (but more can be requested, even if they need another layout to type!)
