Yes, each character code is entered into the alist twice: once with its name, and another time with its "old name", which is empty for most of the characters. I thought the code fragment I posted made that clear. > I see in fact that there are > some `ucs-names' entries that, yes, constitute a pair with the same character > code, yet _both_ are empty. E.g., ("" . 11565) & ("" . 11565). These are undefined characters. 11565 is hex 2d2d; you will not find such a codepoint in the Unicode database.
