Enable Disabled Serbian Latin Google Fontsis a WordPress plugin (download) that enables loading of fonts used by bundled themes (Twenty Thirteen, Twenty Fifteen, Twenty Sixteen, Twenty Seventeen) from Google Fonts that were previously disabled by Serbian language package.
Those fonts were disabled by default because they don’t support Serbian Cyrillic scripts, but since they do support Serbian Latin scripts this plugin re-enables them. Fonts that support both scripts are already enabled while fonts that do not support either script continue to be disabled.
It is a very lightweight, it has no settings, just activate it and it works immediately.
