Page and Form content was decoded tolerantly, keeping what came before a
corrupt spot and dropping the rest without saying so. A page whose content
broke at its first bytes therefore read as empty: the hidden-text scan
counted nothing, the removal was skipped and the original stream, which
other viewers still draw, stayed in the file. Content is now decoded
strictly; an unreadable page counts as something to remove, so the removal
runs and refuses the page, and a Form read only in part is treated like an
undecodable one.
