Perhaps this is a "documentation issue" since I was able to get the PharData() invocation to work when I passed the flag 'CURRENT_AS_SELF'

$reader->setFlags(FilesystemIterator::CURRENT_AS_SELF);

I don't really know whether this is intended behavior or if there is a bug.

The problem is the question mark in the filename
tablepress-combined.min.css?ver=6.css.  This is regarded as the
beginning of a query string[1], so Phar looks for the filename
tablepress-combined.min.css which doesn't exist, because the full
filename has been stored in the Phar's manifest.

Working around by setting CURRENT_AS_SELF helps in this case,
because then phar_path_check() isn't involved.  However, other
means to access the file (e.g. ::__offsetGet()) have the same
issue.

Not sure if this is to be seen as bug or merely a documentation
issue, but it certainly not intended behavior.

And then there is the not directly related issue that question
marks are not valid in filenames on Windows, so extraction would
fail there (same with ext/zip).
