I tested FontForge v20141230 installed from Ubuntu PPA.

I checked location 0x91cf in NotoSans CJK, it's not the right '量' glyph. And checked same location in DroidSansFallback, it's right glyph.

But when I open NotoSans CJK in KDE's font viewer, enter example text '变量'(means 'variable'), it shows the right glyph. I don't understand the mechanism.

Than I checked mplus1p-regular-multilingual.ttf, I found a problem: it contains '量', but missing '变'(0x53d8), it's a common characters too. And I use it to generate PDF for my document, it missing a lot of characters. I think M+ have not enough feedback for Chinese, maybe it's good for Japaness and Korea.

Chinese has a lot of characters, common characters may have several thousand, when contains uncommon characters it comes to several ten thousand, and different regions have different variants (http://blog.typekit.com/2014/07/15/introducing-source-han-sans/). So CJK fonts will be large. NotoSans CJK is the most complete CJK font I know (different regions still need to install different font packages, because all CJK  characters up to 65535 limit. http://www.google.com/get/noto/cjk.html), DroidSansFallback is enough for common CJK use, M+ maybe not enough for Chinese common use.

Thanks for pay attention for CJK, I hope this content will be helpful.
