Bug#241333: policy mentions that changelogs should be utf-8; this is a bug

[Adam Heath <doogie@debian.org>]

package: debian-policy
version: 3.6.0

<dpkg hat on>
Policy 3.6.0 included this in it's changelog:

   * [ACCEPTED]: Debian changelogs should be UTF-8 encoded. Changed the
     wording from a should to a may; since a should would make an unknown
     number of packages insta buggy. A reuest makes all these wishlist
     bugs; we can raise the severity in a later version of policy.
                                                            closes: Bug#174982

This is not supported by any tool in debian.  Control files are ascii, 7-bit,
period.  And, when generating the .changes for an upload, the changelog is
included, this means the changelog *must* be 7-bit ascii.  Period.

Please, remove this from policy.
