Treat \0 as terminator in IPTC strings

[jamesgorrie]

The below image, when passed through exiftool, reads the IPTC Source as "Getty Images North America".

When read with the IptcDirectory we're getting "Getty Images ����". On closer inspection it looks something more like: "Getty Images\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0003\u0000\u0000\u0000\u0005\u0000\u0000\u0000\n����".

The null character is often used to denote the end of a string - is this being respected? Or not as it's not part of the standard?

From looking at the file in a hex editor, it seems that the Getty Images North America string only exists in an IPTC segment and is extracted successfully:

[IPTC - 0x0273] Source = Getty Images North America

What's interesting in this file is that there are actually two IPTC segments. At a glance it seems that the segment with the target string exists within Photoshop data.

It's reasonable that the string you're referring to should treat the first null character as a terminator.
