Ok, I completely missed that part.  So, I suggest switching quotedblleft,
quotedblright, quoteleft and quoteright from unicode_map to extra_unicode_map.

I will also commit something to make that part of the code hopefully clearer,
in particular by referring to 
$Texinfo::Encoding::eight_bit_encoding_aliases{$encoding}
and also such that the point 2 of Alan, 'dashes and quotes appearing in
the document ``, ---, ' as ASCII' is implemented.

Also I think that instead of 'extra_utf8' it could be
'full_coverage_encoding_extra_unicode'
and similarly NO_UTF8_PUNCTUATION could be
FULL_COVERAGE_ENCODING_ASCII_PUNCTUATION.

(But this is a bit long...).
