Hello, I am facing an issue while attempting to utilize UNCSS to eliminate unused CSS styles for the first time. The error message that pops up is as follows:
A Fontconfig warning has been triggered: ignoring C.UTF-8 due to it not being a valid language tag
The error occurs at /home/ubuntu/.nvm/v0.10.35/lib/node_modules/uncss/node_modules/bluebird/js/main/async.js:43 fn = function () { throw arg; }; ^ Error: Fontconfig warning: ignoring C.UTF-8: not a valid language tag
at Socket.onStderr (/home/ubuntu/.nvm/v0.10.35/lib/node_modules/uncss/node_modules/phridge/lib/spawn.js:79:28) at Socket.emit (events.js:117:20) at Socket.<anonymous> (_stream_readable.js:765:14) at Socket.emit (events.js:92:17) at emitReadable_ (_stream_readable.js:427:10) at emitReadable (_stream_readable.js:423:5) at readableAddChunk (_stream_readable.js:166:9) at Socket.Readable.push (_stream_readable.js:128:10) at Pipe.onread (net.js:529:21)
Despite trying Gulp and conducting extensive research in hopes of finding a solution, I am still unable to comprehend the output and its necessary fix.
Any guidance or assistance in resolving this matter would be immensely appreciated.
