emoji

I am working on a chatting application in WPF and I want to use emoticons in it. I am working on WPF app. I want to read emoticons which are coming from Android/iOS devices and show respective images. On WPF, I am getting a black Emoticon looking like . I somehow got a library of emoji icons which are saved with respective hex/escaped unicode values. So, I want to convert these symbols of emoticons into UTF-32/escaped unicode so that I can directly replace related emoji icons with them. I had tried to convert an emoticon to its unicode but end up getting a different string with couple of

I want to add emoji to my site, but hide them if they're not supported on the platform, rather than showing little squares. I have a feeling that this isn't possible, but does anybody disagree? How can this be done? C Try to paint a font (in the Emoji range) to canvas and read a pixel using getImageData . If the pixel's Alpha channel data[3] you're interested-in is not transparent (like for example in the center of ) than might be an Emoji 😗 function supportsEmoji () { var ctx = document.createElement("canvas").getContext("2d"); ctx.fillText("😗", -2, 4); return ctx.getImageData(0, 0, 1, 1)

First I had a UIViewController listenning for the UIKeyboardWillShow notification to adjust the screen for the keyboard. But every time I changed to emoji keyboard, the notification wasn't called. So, I changed to UIKeyboardWillChangeFrame notification like this NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardChanged(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil) It seems to work fine if I just change to emoji by tapping keyboard type. However, if I press and hold keyboard type to select (my keyboard have more than one language) and

前言 只有光头才能变强。 文本已收录至我的GitHub仓库，欢迎Star： https://github.com/ZhongFuCheng3y/3y 如果有看我最近文章的同学可能就知道我在公司负责的是一个消息管理平台(推送系统) 而Push消息是这么多种类型之中非常 重要和常用 的一种类型，最近也希望针对Push推送做些新的尝试，于是去学习学习些Push消息运营的技巧。 这篇文章主要是记一些笔记，以及希望听听你们是怎么看待Push推送的(不妨在评论区留言)。 一、什么是Push消息？ Push消息是非常常见的，每个APP几乎都有此类的产品。举个例子： 二、Push消息能做什么？ 一般我们认为Push消息能做以下的事情： 唤醒用户，提高用户的留存率，提高产品活跃度 。我手机下载了蘑菇街，但我似乎把它已经忘记了(好久没用了)，如果此时这个APP给我推送一条我 有兴趣 的内容。我可能会继续用蘑菇街这个APP，甚至从此活跃起来（购买消费) 告诉用户我有 新的产品上线 了(带动功能模块使用率)。本来蘑菇街是做商城的，现在做起直播来了。但好多用户好像都不咋留意到，此时我推送一条直播的消息给用户，可能用户就爱起直播了。 Push消息能够在你手机闭屏时(即便你没有打开APP)，通过 通知 来给你推送信息，是一种能够 直接触达用户 的消息推送 相对短信而言：成本低、样式多样(支持标题/简介/图片)

How can I truncate a string at a given length without annihilating a unicode character that might be smack in the middle of my length? How can one determine the index of the beginning of a unicode character in a string so that I can avoid creating ugly strings. The square with half of an A visible is the location of another emoji character which has been truncated. -(NSMutableAttributedString*)constructStatusAttributedStringWithRange:(CFRange)range NSString *original = [_postDictionay objectForKey:@"message"]; NSMutableString *truncated = [NSMutableString string]; NSArray *components =

漫话：如何给女朋友解释什么是"锟斤拷"？ ​ 周末女朋友出去逛街了，我自己一个人在家看综艺节目，突然，女朋友给我打来电话。 过了一会，女朋友回来了，她拿出手机，给我看了她在超市拍的照片：  要想知道什么是乱码，需要先从计算机编码说起。 字符编码和ASCII 我们经常看一些谍战剧，谍战剧里敌特、地下党员以及八路军各部间发送情报的时候，一般都是通过电报发送的，电报在传递的过程中，需要发报员用电键发出长短不一的电码，收报员就会听到电报机发出的滴滴滴答答答的声音。其实电报发出的声音都是"滴"和"答"的组合，"答"的声音是"滴"的三倍长。 发报员要先通过一种方式，将想要发送的情报转成电报的滴答声，收报员在听到滴答声之后，再将它们翻译成正常的文字。这个过程就是字符编码和字符解码。 谍战剧中将情报转成电报的"滴"和"答"声主要通过 摩尔斯电码 ，这是一种通过不同的排列顺序来表达不同的英文字母、数字和标点符号的字符编码方式。莫尔斯电码由短的和长的电脉冲（称为点和划）所组成。点和划的时间长度都有规定，以一点为一个基本单位，一划等于三个点的长度。正好对应上电报的"滴"和"答"。 就像电报只能发出"滴"和"答"声一样，计算机只认识0和1两种字符，但是，人类的文字是多种多样的，如何把人类的文字转换成计算机认识的01字符呢，这个过程同样需要通过字符编码。 字符编码（Character encoding

What's the license of OS X Lion's /System/Library/Fonts/Apple Color Emoji.ttf ? In this posting Apple's Peter Edberg says: As previously stated, Apple would like to make the Apple Emoji font - and the glyphs therefrom - widely available using a license that makes it possible for anyone to change it as they see fit or to combine its glyphs with those from another font, without Apple acquiring any rights to such changes. The only conditions we want to impose are: a) The name "Apple Emoji" can only be used for the original unmodified font; if the font is modified or combined with another font,
