Subject: [PATCH] dns.cgi: Revert "dns.cgi: Fixes bug#12395 - German umlauts
 not correctly displayed in remarks"

- This reverts commit 7c6ff5ff12331a53f416080a44c8d6145e78bfac
- That commit removed the cleanhtml command which is not advised, based on feedback from
   Michael Tremer from other patch submissions as it creates a potential security problem.
