Xiaomi's mobile phone emoji displays differently.

It may be the mobile phone system, and some emoticons are not suitable.

Emoji Emoji is not unique to Apple, but the input method is different and the Android version is different. Due to the low version of Android, some special emoticons cannot be displayed. Need to improve the system version, and then use input methods to make emoji expressions, such as Baidu input method, Octopus input method and iFLYTEK input method.
