dns.cgi: Fixes bug#12395 - German umlauts not correctly displayed in remarks
- If Freifunk München e.V. is entered as a remark it gets converted to
Freifunk München e.V.
- This is because cleanhtml is used on the UTF-8 remark text before saving it to the file
and the HTML::Entities::encode_entities command that is run on that remark text does
not work with UTF-8 text.
- If the UTF-8 text in the remark is decoded before running through the cleanhtml command
then the characters with diacritical marks are correctly shown.
- Have tested out the fix on a remark with a range of different characters with
diacritical marks and all of the ones tested were displayed correctly with the fix while
in the original form they were mangled.
