As indicated by the comment <auto-detect/> is here to load the system fonts which we are not supposed to need by default since we embed GNU FreeFont.
It's not all "non-English" characters since it works fine for many of them from what I see but I do reproduce the issue with Chinese characters. And indeed according to https://www.gnu.org/software/freefont/FAQ.html, Freefont does not support Chinese, Japanese, or Korean characters which is quite a limitation by default. I'm not a big fan of enabling back <auto-detect/> since it was taking a lot of memory when loading system fonts (causing https://jira.xwiki.org/browse/XWIKI-13307) which where totally useless for most of them. Ideally we should replace freefont with a more complete font pack if anything like this exist in a compatible license. In any case don't hesitate to create an issue on http://jira.xwiki.org about that.
