What is this CJK app and why is it on my phone? I was going through my apps and discovered this:



Um, what? Unfortunately, I'm not fluent in the language that the app is titled with (Chinese, I'm guessing?), so I have no idea what it is or where it came from. Any ideas? I tend to be careful with what I download (no third-party markets) so I would be surprised if it was malware, but that being said it still looks mighty suspicious to me.

It's a Galaxy Nexus running Android 4.3 if that's relevant.
It looks like it's Google's Pinyin IME. The icon has since changed to use squares instead of circles, but you can still see that it is generally the same, and you can find examples of the old round icon on the Internet still. It's still on the page for Google's Windows variant, in fact:



Google must evidently ship this in their vanilla Android builds for Nexus devices, which would explain why it cannot be uninstalled. This seems to be verified by various sites around the web (one, two, three).
