Subject: [PATCH] aztec scan code in block drawing characters
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Test proper rendering and alignment (which can be verified by external scanner)
of an original 2D code creatable using Barcode Writer in Pure PostScript:

	cat <<-. |
		0 0 moveto (Unicode code) (ecaddchars=2)
		/azteccode /uk.co.terryburton.bwipp findresource exec
	.
	cat /usr/share/libpostscriptbarcode/barcode.ps -

Older 2014 version in Debian needs pre-encoded input to create 15x15 code:

	(10110111000111101010001001000000101001100000100100100000010100110)(raw)

Then converted via PBM to 2x2 box characters:

	pstopnm -pbm -forceplain -stdout -portrait -xsize 15 \
		-llx 0 -lly 0 -urx .42 -ury .42 -xborder 0 -yborder 0 |
	perl -CO -ln -e'
		use utf8;
		/^[01]+$/  or next;
		sub halfbits ($;$) {
			pack "C*", map { $_ << $_[1] } unpack "C*", # multiply values
			pack "(b2)*", split /..\K/, $_[0];  # value of every 2 bits
		}
		($_) = halfbits($_) | halfbits(<>, 2);  # 0..3 + 0,4,8,12
		y/\0-\017/ ▘▝▀▖▌▞▛▗▚▐▜▄▙▟█/;
		print;
	'

Ironically, Aztec Codes do not really support Unicode (raw bytes are
declared to be Latin1), but it's currently the only widely supported 2D code
of this size.
