I only skimmed the spec. But what I gathered, unless I completely
misunderstood the document is that characters from %00 through %1F
inclusive and %7F are control characters and shouldn't be in a URI.
Although they are disallowed within the URI syntax, we include here a
description of those US-ASCII characters that have been excluded and
the reasons for their exclusion.
The control characters in the US-ASCII coded character set are not
used within a URI, both because they are non-printable and because
they are likely to be misinterpreted by some control mechanisms.
control = <US-ASCII coded characters 00-1F and 7F hexadecimal>
So how much trouble would we cause if we just disallowed the entire
range of control characters from URIs? Can anyone think of a real website
that legitimately uses any of these control codes within their URIs? I'm
particularly concerned about shopping sites with their massive URIs.
I still think I would rather have MailScanner do the checking for this
so we can notify the recipient properly, rather than just marking
the message as high spam and/or deleting the message altogether. Perhaps
we could even have MailScanner remove the link code altogether but still
deliver the rest of the message.
Thoughts?
