With the release of iOS 9.1, we got a lot of cool new emoji like taco (🌮)! I'm working on an application where I'd like to show the new emoji characters on devices where they are supported but keep them hidden on devices where they are not. Is there a way to determine if a given emoji character (contained in an NSString) can be rendered on the device the app is running on? After quite a bit of digging on SO and experimenting I've come up with a solution which I will post as an answer below, but please let me know if there's a better way. // Determine if the emoji character provided in the

I'm making my own custom keyboard and I have a problem with adding emoji to it. As a android:keyIcon I have a drawable of that emoji and I need android:codes for it. I don't know what to output when emoji is pressed. I've looked online for a solution, but I haven't found anything. Does anyone know what code should I use to output an emoji. Thanks in advance. Here is a part of the xml code: <Row> <Key android:codes="1F926" android:keyIcon="@drawable/e415" /> <Key android:codes="U+1F601" android:keyIcon="@drawable/e415" /> <Key android:codes="57430" android:keyIcon="@drawable/e0415" /> </Row>

I want to use an American flag emoji in my bash prompt (i.e. PS1 environment variable). However, the American flag emoji causes the terminal cursor to offset an extra character to the right. 🇺🇸 is comprised of two unicode characters, 🇺 and 🇸. I believe terminal is converting this to a mono-spaced emoji character (the flag), yet still allocating space for two characters. How can I achieve my expected cursor position? I want: 🇺🇸 Desktop akirna 🗽 ls| I get: 🇺🇸 Desktop akirna 🗽 ls | << weird space offset before cursor My ~/.bash_profile is: export PS1='🇺🇸 \W \u 🗽 ' Updated Answer The way your are

一， 对emoji表情的理解 emoji表情是一种表情符号，在代码中它现在其实是一组遵循Unicode的编码，即每一个表情符号都对应了一个Unicode编码。更进一步说， emoji表情实际上是一组Unicode编码与一组表情描述之间的一一对应。 注意，这里所说的不是 表情图片 ，而是 表情描述 。那么图片的实现是由谁来负责的呢？图片是由各个系统或者软件针对统一的表情描述来各自实现的，他们都遵循统一的Unicode编码规范。也就是说Unicode编码其所对应的表情描述是统一的，是所有人都要共同遵守的一套标准或者规范，而具体的表情图片则可能因平台的不同而产生差异，比如Android和ios。以非常火的“笑哭”表情为例，如下表 ios Android(>=4.4) Twitter Unicode Description U+1F602 face with tears of joy 对于描述为”face with tears of joy"，Unicode编码为”U+1F602”的表情，ios，android，和twitter分别做了不同的实现。 更过关于emoji表情编码的对应可以在这里找到： http://apps.timwhitlock.info/emoji/tables/unicode 可能需要vpn访问 二， 如何在Android系统中操作系统自带的emoji表情
