Changed Hershey codes 1-26 to small capital unicode.  I could not find small capital unicode for F, Q, S, and X so I left those indices pointing to the normal-sized versions.  I don't know whether I missed something in all the tables I looked up or whether the unicode committees are fighting out where to place these letters, and I invite somebody else to figure out the true story in these 4 cases.
