emoji

I have a UITextView which I call messageField . The data within that messageField is POST -ed to server in JSON format. When the user types an Emoji character I am having trouble encoding the data to JSON . I am thinking Emoji uses Unicode encoding. Is there a way to encode an Emoji character to JSON? And back from JSON to Emoji to display in a UILabel ? Chris Haas Edit - 2016-03-03 Please note, this answer was written in 2011 and may no longer be relevant any more. Emoji characters are just a specific font used to render specific unicode code points. iOS uses one of the Unicode Private Use

最近在做微信相关的项目，其中MySQL 要存储emoji表情，因此发现我们常用的utf8 字符集根本无法存储表情。网上有不少替代方案。本人还是采用了修改MySQL字符集的方案简单快捷。 首先将我们数据库默认字符集由utf8 更改为utf8mb4，对应的表默认字符集也更改为utf8mb4 已经存储表情的字段默认字符集也做了相应的调整。 SQL 语句如： # 修改数据库: ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci; # 修改表: ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; # 修改表字段: ALTER TABLE table_name CHANGE column_name column_name VARCHAR(191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; 其次修改MySQL配置文件 新增如下参数： [client] default-character-set = utf8mb4 [mysql] default-character-set = utf8mb4 [mysqld]

I have a string that looks like this: Now, when my app shoves this string into its utf8 mysql database column, it looks like this in the MySQL CLI: If I select convert(mystring using utfmb4) it still looks like this. And if I turn it to hex using select hex(mystring) from mytable; , it looks like this: C3A2CB9CE282ACC3AFC2B8C28FC3B0C5B8C592CB86C3B0C5B8C592C5A0C3B0C5B8C592C281C3B0C5B8E280A1C2ACC3B0C5B8E280A1C2A7 Now, let's say I want to find strings with that emoji wave in it. Well, the hex for the wave emoji is F09F8C8A . But F09F8C8A isn't in the hex above so something like select * from

I'm trying to convert emojis in hex values, I found some code online to do it but it's only working using Objective C, how to do the same with Swift? This is a "pure Swift" method, without using Foundation: let smiley = "😊" let uni = smiley.unicodeScalars // Unicode scalar values of the string let unicode = uni[uni.startIndex].value // First element as an UInt32 print(String(unicode, radix: 16, uppercase: true)) // Output: 1F60A Note that a Swift Character represents a "Unicode grapheme cluster" (compare Strings in Swift 2 from the Swift blog) which can consist of several "Unicode scalar
