#73 zbar incorrect character display

[Vieri Di Paola]

Hi,

I'm having trouble displaying accented characters with zbar.
Other users have reported the same issue. eg.: http://sourceforge.net/tracker/?func=detail&atid=928516&aid=2884518&group_id=189236
Somehow, the latter thread was closed but if I download the image at:
http://chart.apis.google.com/chart?cht=qr&chs=200x200&choe=UTF-8&chl=%EF%BB%BFR%C3%A9my+Hubscher
(see BOM explanation)
and then run the zbarimg utility, the output isn't correct (I'm expecting "Rémy Hubscher"):
zbarimg --verbose=100 -d chart.png

Any clues?
Is this a known bug or am I doing something wrong?

Thanks

I also compiled the latest code tree from Mercurial and had the same issue.

Today, in version 0.23, ten years later than the last discussion, the bug is still present as experienced on Xubuntu 20.04.2: The letter "ß" appearing in my name is output as a Chinese character ﾃ歹. zbarimg should output as utf-8 by default - or at least should have an option to do so.

There is a clone over at https://github.com/mchehab/zbar which has more development activity (and is probably where your 0.23 came from), maybe you should report the issue there.
