I copied some new fonts files , Apple's PingFang files, many .ttf files, to my CentOS /usr/share/fonts dir and rebuild the font cache via command fc-cache -fv , it seems success. But when I run fc-match 'PingFang', the result is not the newly installed font file. What is the matter?
Another related question is , for the Apple's PingFang family , there are many files, like PingFang Bold.ttf PingFang ExtraLight.ttf PingFang Heavy.ttf PingFang Light.ttf PingFang Medium.ttf PingFang Regular.ttf, what is the right family name for each font file if I want the browser render using specific font file?
