Wingdings is available in OTF format to put on your web site as a webfont: https://www.onlinewebfonts.com/fonts/wingdings_OTF

So is Webdings: https://www.dafontfree.io/webdings-font/

Webdings even got integrated into Unicode 7.0, so all the Noto fonts support it: https://en.wikipedia.org/wiki/Webdings

And recode(1) has full support for ISO-8859-*. As does iconv and the Python3 encodings.codecs module. I'm pretty sure browsers can render pages in them, too. Firefox keeps rendering UTF-8 pages as if they were ISO-8859-1 encoded when I screw up at setting the charset parameter on their content-type.
