There's a couple of things going on here.
One is that this tag isn't conformant to the specifications:
"The count field for each types are defined as follows:
ASCII: The count is the length of the string in bytes including the null
terminator.
Unicode: The count is the number of characters including a Unicode null where a
character is always two bytes."
This is not the case with this tag. The count is longer than the strings for
both strings. This is revealing a "bug" in icclib - it is taking the lengths
of the strings as canonical, instead of the count field. Since the specification
says that the length of the string and the count should be the same, it
has no guidance as to which takes priority if they disagree. I'll
fix the next release of icclib to take the count as canonical (since I guess
this is likely to be the case), and to emit an error if it is compiled
with "STRICT" turned on.
