function isTextSync(filename, buffer) {

		// Extract filename
		const parts = pathUtil

		// Cycle extensions
		for (const extension of parts) {
			if (textExtensions.indexOf(extension) !== -1) {
				return true
			if (binaryExtensions.indexOf(extension) !== -1) {
				return false

	// Fallback to encoding if extension check was not enough
	if (buffer) {
		return getEncodingSync(buffer) === 'utf8'

	// No buffer was provided
	return null
