Many websites package icons into .woff2 or .ttf font files (such as the font packaging services provided by iconfont.cn) to achieve peak performance. While this significantly improves page loading speeds, it often creates a "black box" around the icons, making it difficult for average users or non-professional designers to directly access the SVG source code for individual icons. Support the preview of standard text fonts, allowing you to convert specific character glyphs into icon(svg).
