ALL letters have at least one line of rotational symmetry. However - if you mean reflective symmetry, the letters F, G, J, L, P, Q, R, S, & Z do not.
As with the Roman alphabet, which you may be familiar with it (since you are using it to read this answer), different letters have different symmetries.
H
Not many. Depending on how you write, the letters L, O, Q, and X can have diagonal lines of symmetry.
A, B, C, D, E, H, I, K, M, O, S, T, U, V, W, X, Y all have at least one line of symmetry.
the letters are : E
letter o and x
N, M and H
Seven
o x l I
Lower case "o" and "x" both have two lines of symmetry. Upper case letters with two lines of symmetry are: "O," "X," "H" and "I."
H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.

Four. F, G, J, L
A, v, m, w, y, o, u, x, t, i, h,
H, I, O, X. Of course, it may depend on the font.
