As far as I can see, all of those trip over the warning triggered by
URI​::Escape

In a little over half of these cases, the authors are using Test​:NoWarnings or something similar in their test suites. So they're getting the failure message they requested.

The RT System itself - Status changed from 'new' to 'open'

The latest URI​::Escape no longer issues the warning.

I think this ticket can be closed. The alternative would be to bump the
required version of URI​::Escape in all of these distros when installing a
version of Perl where \C is deprecated.

@iabyn - Status changed from 'open' to 'resolved'
