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.
