Am I right in thinking that
(โ0_0 (: /-\ 0-0โ)
is not a palindrome? The character between the first two zeros is an underline โ_โ. The character between the last two zeros is a dash โ-โ. Donโt the those two characters need to be identical to satisfy the palindrome requirement?
The editor is turning the : + ) characters into a smiley face, by the way, and I donโt know how to prevent this.
