iOS 5: How to convert an Emoji to a unicode character?

由 让人想犯罪 __ 提交于 2019-11-27 02:43:34
I want to convert an Emoji to a unicode character in iOS 5. For example, converting to \ue415 . I went to NSStringEncoding in NSString Class Reference . In iOS 4, NSUTF16BigEndianStringEncoding and NSUTF32BigEndianStringEncoding gave me <e415> and <0000e415> , respectively, which are quite close to what I want. In iOS 5, the results are different. It gaves <d83dde04> and <0001f604> . How can I get \ue415 for in iOS 5? Thank you. \ue415 is part of the legacy encoding for emoji and is specific to certain Japanese carriers. SoftBank, NTT and docomo all had their own private emoji character sets.

问题 I use this table of Emoji and try this code: <?php print json_decode('"\u2600"'); // This convert to ☀ (black sun with rays) ?> If I try to convert this \u1F600 (grinning face) through json_decode , I see this symbol — ὠ0 . Whats wrong? How to get right Emoji? 回答1: PHP 5 JSON's \u can only handle one UTF-16 code unit at a time, so you need to write the surrogate pair instead. For U+1F600 this is \uD83D\uDE00 , which works: echo json_decode('"\uD83D\uDE00"'); 😀 PHP 7 You now no longer need to

问题 I'm working on an Android app, and I do not want people to use emoji in the input. How can I remove emoji characters from a string? 回答1: Emojis can be found in the following ranges (source) : U+2190 to U+21FF U+2600 to U+26FF U+2700 to U+27BF U+3000 to U+303F U+1F300 to U+1F64F U+1F680 to U+1F6FF You can use this line in your script to filter them all at once: text.replace("/[\u2190-\u21FF]|[\u2600-\u26FF]|[\u2700-\u27BF]|[\u3000-\u303F]|[\u1F300-\u1F64F]|[\u1F680-\u1F6FF]/g", ""); 回答2:

问题 I'm trying to encode and decode Emojis to send them to my database. I use this to encode: var comentario = String() let data = Comment.data(using: String.Encoding.nonLossyASCII, allowLossyConversion: true) if let data = data { let emojiString = NSString(data: data, encoding: String.Encoding.utf8.rawValue)! as String comentario = emojiString } And it works. But now I don't know how to decode the emoji. This is the type of encode ---> \ud83d\ude1a 回答1: Your encoding code can be simplified to

Swift countElements() return incorrect value when count flag emoji

由 梦想与她 提交于 2019-11-27 01:37:12
let str1 = "🇩🇪🇩🇪🇩🇪🇩🇪🇩🇪" let str2 = "🇩🇪.🇩🇪.🇩🇪.🇩🇪.🇩🇪." println("\(countElements(str1)), \(countElements(str2))") Result: 1, 10 But should not str1 have 5 elements? The bug seems only occurred when I use the flag emoji. Update for Swift 4 (Xcode 9) As of Swift 4 (tested with Xcode 9 beta) grapheme clusters break after every second regional indicator symbol, as mandated by the Unicode 9 standard: let str1 = "🇩🇪🇩🇪🇩🇪🇩🇪🇩🇪" print(str1.count) // 5 print(Array(str1)) // ["🇩🇪", "🇩🇪", "🇩🇪", "🇩🇪", "🇩🇪"] Also String is a collection of its characters (again), so one can obtain the character count with str1

How can I split a string containing emoji into an array?

问题 (You'll need Firefox or Safari to see the emoji in the code.) I want to take a string of emoji and do something with the individual characters. In JavaScript "😴😄😃⛔🎠🚓🚇".length == 13 because "⛔" length is 1, the rest are 2. So we can't do s = string.split(""); c = []; c[0] = s[0]+s[1]; Here's what I made: 回答1: The grapheme-splitter library that does just that, is fully compatible even with old browsers and works not just with emoji but all sorts of exotic characters: https://github.com/orling

Is there a way to know if an Emoji is supported in iOS?

由 痞子三分冷 提交于 2019-11-26 22:53:45
问题 I'm building an iOS App, and Emojis play a big part in it. In iOS 10.2, new emojis were released. I'm pretty sure that if someone has iOS 8, for example, they wouldn't actually be able to see these emojis. Is there a way to detect this? I'm trying to dynamically build a list of all the Emojis that are supported on the user's iOS version, but I'm having a bit of trouble. 回答1: Clarification: an Emoji is merely a character in the Unicode Character space, so the present solution works for all

Printing emojis with JavaScript and HTML

问题 Why does this work: <p id="emoji">😄</p> And this doesn't: document.getElementById("emoji").innerHTML = String.fromCharCode(parseInt('1f604', 16)); 回答1: A 'char' in JS terms is actually a UTF-16 code unit, not a full Unicode character. (This sad state of affairs stems from ancient times when there wasn't a difference*.) To use a character outside of the Basic Multilingual Plane you have to write it in the UTF-16-encoded form of a surrogate pair of two 16-bit code units: String.fromCharCode
