I got two problems:one was that a question mark would be found in the front of the information embedded when it contained a chinese character at least;the other was that,I got nothing when it contained more than sixty-six characters including punctuations,blank spaces.Can you give me some suggestions?Thanks in advance.
i had thee same problem with Lithuanian symbols.
Here is the patch: add
just after qr_hints.put(EncodeHintType.ERROR_CORRECTION, qr_quality);
in the 'encode_qr.m'
It will probably make QR code unreadable by any other QR decoder, except ZXing's.
