emoji

I recently upgraded to Xcode 8 and converted my code to Swift 3. I am making a custom keyboard (extension) which worked perfectly fine till iOS 9, but i am facing a couple of issues in iOS 10. The container app of the custom keyboard contains a button which directs the user to the keyboard settings to add the keyboard Issue: This button click is not working in iOS 10 i.e the user is not directed to the settings. I have configured the URL Schemes in my project and have tried the following code : @IBAction func btnGetStarted(_ sender: AnyObject) { let settingsUrl = URL(string:

I'm looking for a way to replace emoji characters with their description in a Swift string. Example: Input "This is my string 😄" I'd like to replace the 😄 to get: Output "This is my string {SMILING FACE WITH OPEN MOUTH AND SMILING EYES}" To date I'm using this code modified from the original code of this answer by MartinR , but it works only if I deal with a single character. let myCharacter : Character = "😄" let cfstr = NSMutableString(string: String(myCharacter)) as CFMutableString var range = CFRangeMake(0, CFStringGetLength(cfstr)) CFStringTransform(cfstr, &range,

I am trying to develop an application for both iOS and Android with emoji support in posts. Currently I am Base64 encoding and decoding the String (text &/ emoji) with UTF-8. It seems to work natively, Android-to-Android and iOS-to-iOS, but from Android -> iOS or iOS -> Android it doesn't always work. There are occasionally a few emojis missing, and the rest of the string (any actual text) is lost in these instances. Note: I understand different devices have different emojis, so I am not as worried about occasional missing emojis, but the missing text bothers me, and I noticed a missing emoji

1997年，日本人发明，定义在unicode的私有区域。 此时两个字节可以表示emoji。 IOS 4在日本支持emoji，使用的是这种私有编码。 2010年，unicode 6.0正式支持emoji，所有emoji重新编码。 此时的emoji所在的编码范围超出了2个字节。 IOS 5开始，支持unicode的emoji，放弃对日本人的私有emoji支持。 所以，同一个emoji，尤其是老的那些emoji，有两个编码。 不同系统的支持情况，不一样。 emoji的编码虽然相同，但是样子都是有专利的，因此各个系统，展示起来可能各不相同。 因为unicode的emoji超出了2个字节的表示范围，很多系统需要字符编码才能支持emoji。比如mysql，在更新了utf8mb4之后才支持。 日本人的编码，其实也不止一种，如果想要你的emoji在所有系统都能展示，需要你在展示的时候做转换。 emoji的发展历程、unicode编码演化、以及各种系统对字符串编码格式支持的变迁，三者交互在一起，引发各种有趣的问题。几乎每一次emoji不能展示，背后都与这三者相关。 因为涉及到系统底层的编码支持，很多时候问题不好解决。 本来想细细地写一篇文章，最近身体不适，精力不允许了。感兴趣的阅读下我列出的参考资料，很有意思。 Reference https://gist.github.com/mranney

Question My question, explained below, is how can R be used to read a string that includes HTML emoji codes like &#55358;&#56599; , and either (1) represent the emoji symbol (e.g., as a unicode symbol: 🤗 ) in the parsed string, or (2) convert it into its text equivalent (" :hugging face: ")? Background I have an XML dataset of text messages (from the Android/iOS app [Signal])( https://signal.org/ ) that I am reading into R for a text mining project. The data look like this, with each text message represented in an sms node: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!-- File

I am trying to insert emoji / emoticons to MSSQL database but it just stores ??? instead of the emoji / emoticons. I am finding only help for MSSQL not MySQL I tried : link but not finding answers even not able to set with : ALTER TABLE mytable charset=utf8mb4, MODIFY COLUMN textfield1 VARCHAR(255) CHARACTER SET utf8mb4,MODIFY COLUMN textfield2 VARCHAR(255) CHARACTER SET utf8mb4; MSSQL does not recognize this command. this is only for Microsoft SQL server not MySQL Use NVARCHAR(size) datatype and prefix string literal with N : CREATE TABLE #tab(col NVARCHAR(100)); INSERT INTO #tab(col) VALUES

I'm working on default emojis in iOS. i'm able to successfully encode and decode default emojis using NSNonLossyASCIIStringEncoding encoding. Its working fine when i sent emojis with simple text but it returns nil when some special character is added in string. How do i make it work ? Code : testString=":;Hello \ud83d\ude09\ud83d\ude00 ., <> /?\"; NSData *data = [testString dataUsingEncoding:NSUTF8StringEncoding]; NSString *strBody = [[NSString alloc] initWithData:data encoding:NSNonLossyASCIIStringEncoding]; // here strBody is nil The problem is due to different encodings you have used for
