如何通过单词引用iconfont中的字形？

Question

I want to use iconfont in my project,and custom the font file by fontforge.

I know glyph can be referenced by unicode in html or css, such as <i>&#xe030;</i> and &::before{content: "\\e030";} .While I find some people can reference glyph by this: <i>library_music</i> .I guess that's glyph name, but I cant find the 'library_music' definition in fontforge.

Here is my html and css code.

 @font-face { font-family: 'testfont'; src: url(https://fonts.gstatic.com/s/materialicons/v48/flUhRq6tzZclQEJ-Vdg-IuiaDsNc.woff2) format('woff2'); } i { font-family: "testfont"; } 

 <i>library_music</i> <i>&#xe030;</i> 

I hope some one can tell me what is the principle of 'library_music' reference and how can I custom the word in fontforge.

thx a lot.
