Wingdings is a dingbat font included in Microsoft Windows 3.1+, substituting
letters by shapes and symbols which in turn have all been encoded in Unicode
version 7.0.
Show the results for capital letters A-Z for a general impression of these
glyphs (as listed on <http://www.alanwood.net/demos/wingdings.html>),
although lowercase a-z are also commonly used in this kind of obfuscation.
