Chinese characters (a.k.a CJK unified ideographs in Unicode) are not only used in China. In different regions, the same characters can be written in different shapes. Fonts for Chinese character is those regions will reflect these differences.

"Other languages" include but may not be limited to Japanese (Japan), Chinese Traditional (Hongkong), and Chinese Traditional (Taiwan). Like this in Chrome:
If you don't put Chinese Simplified there, or put some of those "other languages" above Chinese Simplified, you are likely to have such issues.
