Most simple alphabetic languages are currently well served by existing Web font delivery methods. However, the Chinese, Japanese and Korean (CJK) group of languages is currently unable to use Webfonts due to the very large file sizes. A substantial reduction in file size is needed, without a significant increase in page load times caused by multiple network requests. Please implement Incremental Font Transfer (IFT) for webfont loading: https://www.w3.org/TR/IFT/
