I don't know what PDF you're talking about.  Are you referring to a
specific example PDF?  to a (common?) form of translation between ASCII
text streams and PDFs?  to something else?

The goal of the whitespace canonicalization as i understand it is
*exactly* this -- that regardless of how the unprintable characters show
up (or don't), a valid signature will be seen as valid.

However, the thing that is validated is the canonicalized version, not
any of the potential whitespace variants.
