emoji

在微信开发过程中，有些用户的昵称是特殊表情，导致服务器端存储时发生错误： Caused by: java.sql.SQLException: Incorrect string value: '\xF0\x9F\x98\x84' for column 'review' at row 1 at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1074) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4096) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4028) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:2490) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2651) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2734) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:2155) at

Java 获取到微信端传递过来的Emoji表情插入MySQL之后报错 ， 错误信息如下 java.sql.SQLException: Incorrect string value: '\xF0\x9F\x92\x94' for column 'name' at row 1 at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1073) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3593) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3525) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1986) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2140) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2620) at com.mysql.jdbc.StatementImpl.executeUpdate(StatementImpl.java:1662) at com.mysql.jdbc

I have a method that detects urls in a string and returns me both the urls and the ranges where they can be found. Everything works perfectly until there are emojis on the string. For example: "I'm gonna do this callenge as soon as I can swing again 😂😂😂\n http://youtu.be/SW_d3fGz1hk" Because of the emojis, the url extracted from the text is http://youtu.be/SW_d3fGz1 instead of http://youtu.be/SW_d3fGz1hk . I figured that the easiest solution was to just replace the emojis on the string with whitespace characters (cause I need the range to be correct for some text styling stuff). Problem is,

I have an issue with one of my current weekend projects. I am writing a Python script that fetches some data from different sources and then spits everything out to an esc-pos printer. As you might imagine pos printers don't exactly like emojis... So text like this: 可爱!!!!!!!!😍😍😍😍😍😍😍😝 gives me this character string: '\u53ef\u7231!!!!!!!!\U0001f60d\U0001f60d\U0001f60d\U0001f60d\U0001f60d\U0001f60d\U0001f60d\U0001f61d' The result that comes out of the printer is quite different than what I would like of course. So I need to replace these non-ASCII characters with something else. I don't really

I'm facing a problem about displaying emoji in a UILabel. I get this data from a web service (i cannot change the way i get the data) : This value is from the debugger : __NSCFString * @"emoji \\ud83d\\ude1b\\ud83d\\ude1d" 0x000000017405ea80 Value from NSLog : emoji \ud83d\ude1b\ud83d\ude1d if i assign this value to my UILabel text property i get on the screen : emoji \ud83d\ude1b\ud83d\ude1d I tried to encode and decode the string using : NSData *data = [string dataUsingEncoding:NSNonLossyASCIIStringEncoding]; NSString *dataValue = [[NSString alloc] initWithData:data encoding

I have found some unexpected differences when printing, via print , a string with a family emoji directly, and when it's in a list. The below program family = '👨‍👩‍👧‍👧' print(family) print([family]) outputs 👨‍👩‍👧‍👧 ['👨\u200d👩\u200d👧\u200d👧'] when I would expect it to output 👨‍👩‍👧‍👧 ['👨‍👩‍👧‍👧'] Another case of multi-character glyph man_with_skin_tone_modifier = '👨🏿' print(man_with_skin_tone_modifier) print([man_with_skin_tone_modifier]) outputs as I expect: 👨🏿 ['👨🏿'] Why is this? Context: I discovered this while writing the answer for https://stackoverflow.com/a/49930688/1319998 , and it's

01、前言 Emoji 在我们生活中真的是越来越常见了，几乎每次发消息的时候不带个 Emoji，总觉得少了点什么，似乎干巴巴的文字已经无法承载我们丰富的感情了。对于我们开发者来说，如何将 Emoji 存入 MySql 数据库或者取出来，就变成了一种必须掌握的技能了。 Emoji 是一种图形符号，能够很直观地反应出某种文字含义。它让我想起远古时代的象形文字。 1 16.3 KB Emoji 其实是一个日语词（えもじ）， E 表示"絵"， moji 表示"文字"；连在一起就是"絵文字"，可以更形象化地表情达意。 02、糟糕 如果我们直接将 Emoji 表情存入数据库的话，通常会出现下面这个错误。 1 6.1 KB 因为数据库的字符编码一般是 utf8（支持的编码范围为 \u0000-\uFFFF ），而 Emoji 所在的编码范围是 \u1F601-\u1F64F ，超出 MySql 的边界了。 怎么解决这个问题呢？ 03、utf8mb4 可以将 MySql 的字符集由 utf8 调整为 utf8mb4。utf8mb4 是 MySql 在 5.5.3 版本之后增加的一个编码方式，用来兼容四字节的 Unicode（包括 Emoji）。 理论上，utf8mb4 是 utf8 的超集，其中 mb4 是 most bytes 4 的意思，将字符集修改为“utf8mb4”，并不会对已有的

I wanted to disable the emoji keyboard programmatically. please let me know how can i do that ? I tried using following code, NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"]; [dict setObject:[NSNumber numberWithBool:NO] forKey:@"KeyboardEmojiEverywhere"]; But no luck ... :( You can simply set the property keyboardType of the UITextField or UITextView to UIKeyboardTypeASCIICapable. This disables the Emoji Keyboard for this UI element. This may not work in chinese how ever we have a workaround
