Re: [Unicode-2] `C-h f' error

[Richard Stallman]

    Make the Lisp reader to generate a symbol of unibyte name
    when it is read from a unibyte buffer.  Previously, the
    multibyteness of a symbol name is determined by the byte
    sequence (by using make_string).

Please add a comment explaining the bad results that happened
when we tried the other way.  (Unless you already did so.)
It is very important to explain this IN the source file.
