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 remark text before saving it to the file and
the HTML::Entities::encode_entities command that is run on that remark text encodes all
higher bit characters as unsafe characters and replaces them with their HTML entity
representation.
- Have tested out the remark with a range of different characters with diacritical marks
and all of the ones tested were re-written.
- The use of the cleanhtml makes sense when used on URL's or on text that is going to be
printed as part of the HTML code for a page but it doesn't seem to make sense for text
used in a remark.
- The cleanhtml function is only used on the remark text in dns.cgi and not on any other
entries on the page.
- Removing the call to the cleanhtml function results in the German umlauts being printed
in the remark section.
- Many of the WUI pages have the cleanhtml function used on remark or comment text.
- fwhosts.cgi does not use cleanhtml anywhere. So all its remark sections work with
characters with diacritical marks.
- If this patch is accepted, I will then submit patches for the other WUI pages where
characters with diacritical marks are re-written in remark or comment sections.
