hold them up to a mirror and copy what you see
write them backward incuding the letters and then they look normal in the reflection
backward foreward toward untoward
Otto...
put a mirror next to it. Its pretty simple the letters are formed backward. I can write in all four directions in cursive. Forward, backward, upside-down forward, and upside-down backward.

Answer is one because DE is the only example of such a pair of letters.

Why
I don't believe there is such a font available. The easier way - would be to create the palindrome using Microsoft Paint. You can manipulate the letters as you see fit.
If they read the same, they're called palindromes.
