(collate) is not the same, so you need to specify the rules of comparison, utf8mb4_unicode_ci is utf8mb4 the character set corresponding to the comparison rules. For example, if the character set is a utf8mb4 database, execute the SQL statement: select * from boy where name=‘xueweihan‘ you need to filter the records in the database with the specified collate rules.Use PostureTo create a database:CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;To connect to a database
How to make a emoji expression on a Mac? Apple's emoji expression is the first to be introduced and is undoubtedly the best of its kind. Another advantage of his is that there is no use of any tool software, is the system's own functions, support text editing and network applications, and can achieve fast input, see here I believe you will have a lot of interest. The following small compilation teaches ever

After checking, the binary format of these strings is as follows:What do you see in binary Unicode ? 14> unicode:characters_to_list ([128518,128528]15> erlang:integer_to_list (128518,16).

If the UTF8 character set is a Java server, when the store contains a emoji expression, it throws an exception similar to the following:Java.sql.SQLException:IncorrectStringValue' \xf0\x9f\x92\x94 'For column' Name ' at row1 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.se
Mobile input allows input expression, the expression is actually UTF-16 encoding, in the database storage will be lost, currently if the database Loadline code modified to UTF8MB4 can also be saved.If you do not want to modify the others, you can convert these emoji to the HTML character entity save.The code is as follows:Functionutf16_to_entities () { $content =mb_convert_encoding ($content, ' utf-16 '); $bin =bin2hex ($content); $arr = str_split ($
Reason:The UTF-8 encoding can be two, three, and four bytes. The emoji expression is 4 bytes, while MySQL UTF8 encodes up to 3 bytes, so data cannot be plugged in.Workaround:Convert MySQL encoding from UTF8 to UTF8MB4Steps:1. Modify the MySQL configuration file My.inidefault-character-Set=utf8mb4character-set-SERVER=UTF8MB42. Join[Client]port=3306default-character-Set=Utf8mb4[mysqld] Add character -Set-client-handshake= falsecollation-server= utf8mb4_
But we can replace it with a regular:
Copy the Code code as follows:
function Dhtmlspecialchars ($string) {if (Is_array ($string)) {foreach ($string as $key = = $val) {$string [$key] = Dhtmlspecialchars ($val);}} else {$string = Preg_replace ('/ (# (\d{3,5}|x[a-fa-f0-9]{4}) |[ a-za-z][a-z0-9]{2,5});)/', ' \\1 ',Str_replace (Array (' ', ' ' ', ' }return $string;}?>
