Abbreviationes™ can be used on any device with a standards-compliant Web browser (Windows, Mac, Linux, and Mobile). Abbreviationes™ uses WebFonts¹ to let you key in abbreviations with superscript letters or special abbreviation marks, and to display these characters properly. WebFonts is supported by Microsoft Internet Explorer (any version from 4.0 through 11.0), Microsoft Edge (version 20 or higher), Apple Safari (version 3.1 or higher), Mozilla Firefox (version 3.5 or higher), and Google Chrome (version 4.0 or higher).² In addition, Abbreviationes™ is optimized for the mobile versions of Internet Explorer, Microsoft Edge, Safari, Firefox, and Chrome on smartphones such as Apple’s iPhone, Google’s Pixel, or Microsoft’s Lumia.³

¹ WebFonts is a technology for automatically loading fonts over the Web, without requiring users to separately download and install fonts to their operating system (http://www.w3.org/Fonts/). WebFonts allows you to load fonts for use in a Web page, just like you would load images. This technology was first available in Netscape Navigator 4 and Microsoft Internet Explorer 4. Unfortunately, neither Netscape nor Microsoft supported TrueType, the most widely used font format. Netscape licensed Bitstream’s TrueDoc technology and its proprietary Portable Font Resource (.pfr) format, while Microsoft developed their own Embedded OpenType (.eot) format.
Today, Apple Safari, Mozilla Firefox, Google Chrome, and Microsoft Edge all support the popular TrueType Font (.ttf) and OpenType Font (.otf) formats using the CSS3 @font-face rule; in addition, Safari supports the Scalable Vector Graphics (.svg) font format, which is an open W3C standard. Microsoft Internet Explorer continues to support Embedded OpenType (.eot) fonts. However, since version 9.0, Internet Explorer also supports TrueType (.ttf) and OpenType (.otf) fonts.
² For best compatibility, Abbreviationes™ uses Embedded OpenType fonts for Internet Explorer up to version 10, and TrueType or SVG fonts for all other Web browsers, including Internet Explorer 11 and Microsoft Edge.
³ WebFonts is supported by Safari Mobile (any iPhone running iOS 3.1 or higher), Firefox Mobile (version 4 or higher), Chrome Mobile (Android 4.1 or higher), Internet Explorer Mobile (Windows Phone 8 or higher), and Microsoft Edge Mobile (Windows 10 Mobile).
