For modern scaleable UI applications, it helps a lot when one has a consistently designed scalable icon set with icons having the same dimensions and features.
In more than just one sense, designing and developing such sets is a lot like developing and designing scaleable fonts. It is not surprising that by now many of these are available as fonts.
Ons of them is [Wayback/Archive] Segoe Fluent Icons font – Windows apps | Microsoft Learn which on the page has the complete list: an impressive one indeed and as such a leap from the old dingbat fonts like Zapf Dingbats fonts (yes, I am more than ITC Zapf Dingbats old; most glyphs ended up in the Dingbats (Unicode block) in 1991), Wingdings from Microsoft Windows 3.1 on, Wingdings 2 and Wingdings 3 in Microsoft Office versions until Office 2010, and the – now part of Core fonts for the web – Webdings as of Internet Explore 4.
Those old fonts only had small sets of icons – usually no more than 230, some just dozens – and Segoe Fluent Icons has a huge set of icons.
