Describe the bug
It is great, but not support Chinese and Japanese.

To Reproduce

Just add a Chinese or Japanese keyboard then switch to it, type any words in CocoaTextField, the first word is correct, type one suggestion word, then type any words always are English.

Ideas:

• Set a minimum dimension for images.
• Find a way to detect dimensions before downloading the image.

Currently, the framework is lagging unit testing. Add some unit test.

Help welcome to add more tests :)
