----------------------------------------------------------------
{quote}The cause is a comment in a content stream. I doubt that this is legit:
"Any occurrence of the PERCENT SIGN (25h) outside a string or stream introduces
a comment".{quote}
It is valid.
You quote from ISO 32000-1. Already here that was an error as one can see in
some example content streams, e.g. the colored tiling pattern examples.
In ISO 32000-2 that has been changed to
{quote}Any occurrence of the PERCENT SIGN (25h) outside a string or inside a
content stream (see 7.8.2, "Content streams") introduces a comment.{quote}
which isn't that much better as it, strictly speaking, even makes `%`s in
arbitrary binary streams starts of comments. Which is not intended of course.
A clarification hereof has been the topic of
https://github.com/pdf-association/pdf-issues/issues/273 for quite a while now.
