It's wrong visually, because I know the syntax for strings in Emacs 
Lisp, and I know that "\x905" is supposed to be a 1-character string 
whereas "\2205" is a two-character string.

The difference is that I don't use display tables and don't want to use 
them. In contrast, I would like to use hexadecimal display, if it worked 
as well as octal does (which it does not).
