Accessing Google Early Access Fonts

Hello. I have made a feature request regarding this issue but decided to pursue it myself by modifying the fonts.json. I followed the preexisting format to link Google Early Access Fonts by adding the following lines (based on the information found in CSS of the target font) starting at line 4: { "kind": "webfonts#webfont", "family": "Nanum Gothic", "variants": [ "400", "700", "800" ], "subsets": [ "latin", "korean" ], "version": "v4", "lastModified": "2014-01-07", "files": { "400": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanumgothic/v4/NanumGothic-Regular.eot", "700": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanumgothic/v4/NanumGothic-Bold.eot", "800": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanumgothic/v4/NanumGothic-ExtraBold.eot" } }, Now, this works flawlessly, showing the assigned font as the very first font on the drop list of the font customizer screen. However, when I tried to add the next font, just below the new custome font and above ABeeZee as follows, the font name is visible but cannot be applied: { "kind": "webfonts#webfont", "family": "Nanum Myeongjo", "variants": [ "400", "700", "800" ], "subsets": [ "latin" ], "version": "v3", "lastModified": "2014-01-07", "files": { "400": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanummyeongjo/v3/NanumMyeongjo-Regular.eot", "700": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanummyeongjo/v3/NanumMyeongjo-Bold.eot", "800": "http://themes.googleusercontent.com/static/fonts/earlyaccess/nanummyeongjo/v3/NanumMyeongjo-ExtraBold.eot" } }, I know I am not a programmer and I accidentally came across this in an attempt to apply Korean font not available in Google Fonts, but I don’t understand why the first one works while the successive one fails. Can you see the flaws? https://wordpress.org/plugins/google-web-fonts-customizer-gwfc/
