Re: [PATCH] Unicode Lisp reader escapes

[Richard Stallman]

    The initial `#' character is a valid Emacs hash notation for writing
    integers in various bases.  After adding `\uXXXX' it seems reasonable
    to add `#\uXXXX' as well.  However, there is one difference: Emacs Lisp
    hash notation doesn't use the backslash `\' after `#', e.g. `#x42',
    but other Lisps use the backslash in the notation of Unicode characters,
    e.g. `#\u3042'.  I have no opinion which notation is better.

I think it is better to consistent with the existing Emacs Lisp
constructs.
