Wingdings font should not be used in Web pages…, use Unicode instead.
OpenType version of Wingdings with Vista, XP and 2000, an older TrueType version with 3.1x, 95, 98, ME and NT. A resource-fork TrueType version with versions Mac OS 9 that had Internet Explorer as the default Web browser.

Chrome, IE and Netscape 4 and Safari (are not standards-compliant) allow non-Unicode fonts such as Wingdings which is contrary to the specifications.
Wingdings is not available on all computers. The intended characters are also unlikely to appear when using a standards-compliant browser such as Firefox, Netscape 6+, Opera 6+ or SeaMonkey (formerly Mozilla). The same problems are found with the Webdings, Wingdings 2 and Wingdings 3 fonts – they should not be used in Web pages. This page lists (and attempts to display) all of the 224 characters in the Wingdings font. It also lists (and attempts to display) the equivalent Unicode characters, where these exist. Not all Wingdings characters have equivalent Unicode characters, and some of the listed β€œequivalents” are not very good matches. The characters that appear in the Wingdings Character column of the following table are generated by the non-standard technique of specifying the Wingdings font, using . It is possible that your combination of browser and operating system will show special characters, but browsers that conform to the published standards will demonstrate why Wingdings font should not be used in Web pages. The characters that appear in the Unicode Character column of the following table are generated from Unicode numeric character references, and so they should appear correctly in any Web browser that supports Unicode and that has suitable fonts available, regardless of the operating system.
