Command line tool can't encode NULL bytes about libqrencode

[d4ndo]

What are you doing? Looks like a »null byte injection« ;)
I'm not sure, if the NULL byte is supported by the qrcode specification.

@d4ndo : See the section "Encoding a string/data" on http://fukuchi.org/works/qrencode/manual/index.html . As you can see, the library supports NULL bytes, but the command-line tool doesn't.

Hi @ysangkok,

Current implementation of the command line tool does not support NULL byte because it only accept data input via standard input. When I started to develop it, I did not think binary data including NULL will be used.

I think it is not so difficult to support it. Please wait for a couple of week, or patches are welcome.

Some additional information:
Using the 8bit mode worked out. It did not return an error. But I'm not sure if the output »qrcode« is correct.

$ echo -en "\x00" | qrencode -8 -t PNG -o lol.png

Gee, I completely forgot that we already fixed the problem by a0e1dfb

@ysangok, please follow @d4ndo 's instruction. Thank you, @d4ndo.
