What is an Emoji
emoji emoticons is ; meaning from the Japanese (SHRIMPSもじ, e-moji, moji meaning is in Japanese characters )
emoticons are now widely used in mobile phone text messages and Internet chat software.
emoji emoticons, SMS abroad is an expression which has been very popular use.
on the phone how to use emoji:
1.iphone, ipad systems : installation emoji free, then Settings - General - Keyboard - International Keyboards - add a new keyboard, and then add on the inside to put emoji in texting and some input text in the text box enter the expression.
IOS 5 users can add emoji keyboard directly from GM , the need to install emoji free
2.android Systems: Installation "GO Keyboard International Edition " post , in which tap input method can be used to install emoji plugin . In addition, " Baidu input method" also comes with emoji expressions
3.Windows Phone: install Emoji Keys, in which the need to copy and paste the following input where you can enter expressions

Emoji Emoticons two issues
1 issue : Emoji emoticons sent between
IOS versions are not compatible , only to see the box
different IOS versions in the data inventory data , system error occurs sometimes
2 phenomenon :
IOS 4 input Emoji emoticons , display properly in IOS5.01 in IOS5.1 (the mainland version ) appears as a block , but IOS5.01 / 5.1 emoticon input , display normal
IOS5.01/5.1 enter emoticons , display properly in IOS5.01/5.1 , but it appears as a block in IOS4.X
Emoji input into the post body , can be properly stored . but the user nickname IOS4.X input Emoji, the system is normal, but IOS5.01/5.1 prompt the system error.
3 nature :
iOS 5 and OS X 10.7 (Lion) use the Unicode 6.0 standard 'unified' code points for emoji.
iOS 5 Emoji using Unicode 6 standard uniform code points
iOS 4 on SoftBank iPhones used a set of unofficial code points in the Unicode Private Use Area, and so aren't compatible with any other systems
iOS 4 using SoftBank Unicode, unofficial , using Unicode private area .
4 Example:
one emoji symbol "tiger", it is "\ U0001f42f" in iOS5, but "\ ue050" ; in earlier iOS version
tiger face Emoji symbols in iOS5 as Unicode: \ U0001f42f; while IOS4.x as : \ ue050 (SoftBank encoding )
Also: Logically speaking, from iOS5 should be compatible with previous versions of emoji, but now appear perfectly compatible with version 5.01 ( regardless of the mainland version , the U.S. version , or the Hong Kong version ) , while the mainland version 5.1 is not compatible with the emergence of the phenomenon ( Tencent micro-channel also appeared in the same issue ) .
three problem analysis
1 system storage error problem ( such as a nickname, post content )
reasons:
Since IOS5.X adopt new Unicode, UTF8 encoding its mostly four bytes , and as a nickname / post content column did not set utf8mb4, Therefore, storage errors will occur.
Solution:
The nickname / post content set utf8mb4
between two different iOS Emoji incompatibility issues .
reasons:
iOS 5到4 Not compatible problem is very simple, and softbank encoding different unicode6
iOS 4 to 5 arguably should be compatible , ie , iOS softbank should automatically determine if it is coded to automatically turn into unicode6. But now it seems , iOS5.1 ( mainland version ) seems to only support unicode6, without support softbank.
Solution:
client sends emoji-encoding: Softbank or unicode6, the server gives the corresponding code table respectively .
four solutions
1 data storage (MySQL varchar data type support issues UTF8)
MYSQL prior to 5.5, UTF8 encoding supports only 1-3 bytes, from the beginning MYSQL5.5 can support 4 -byte UTF encoding , but to a special tag. For example, our post content items , we add this support. Mysql server is unified storage is ios5.x Unicode encoding.
corresponding alter statement:
ALTER TABLE topic MODIFY COLUMN content varchar (500) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT ' content ' ;
2 transcoding :
iphone mobile solutions
client input content when stored as a unified unicode encoding ( here need to be converted to unicode encoded softbank coding ) . When a client requests content , depending on the needs of the client is given a different encoding , ios4 encoded using softbank do replace , direct support ios5 using unicode encoding.
android or wp other mobile solutions :
If you do not emoji expression database , you can not enter . For input problem, using unicode encoded unified storage . When a client requests content , will be unified with softbank encoding , the client needs to emoji emoticons built into the client , do the coding and replace the corresponding img .

in principle there is no problem in terms of a total of 467 emoji is no problem , because my method is a generic method , I found softbank to utf-8 encoding conversion rules.
ios5 hair and I just used the flag with the flag icon seen android phone , no problem.
Although I did not test the 467 icons , but I think there is no problem .
