Can't insert some special characters into mysql

The value cut off after that character đź’€

Why this happening?

create table tmp2(t1 varchar(100)); 

insert into tmp2 values('befoređź’€after'); 

mysql> select * from tmp2; 
+--------+ 
| t1 | 
+--------+ 
| before | 
+--------+ 
1 row in set (0.01 sec)

I ran followed commands and returned some useful information

mysql> SHOW FULL COLUMNS FROM tmp2;
+-------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+
| Field | Type         | Collation       | Null | Key | Default | Extra | Privileges                      | Comment |
+-------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+
| t1    | varchar(100) | utf8_general_ci | YES  |     | NULL    |       | select,insert,update,references |         |
+-------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+
1 row in set (0.00 sec)

and this,

mysql> SELECT character_set_name FROM information_schema.`COLUMNS` WHERE table_schema = "test" AND table_name = "tmp2" AND column_name = "t1";
+--------------------+
| character_set_name |
+--------------------+
| utf8               |
+--------------------+
1 row in set (0.00 sec)

Im testing this on ubuntu/mysql command line.

I found the solution here

I learnt some characters are not includes in utf8

There is a good article here

I needed to change column utf8 to utf8mb4 and it worked

alter table tmp2 modify t1 varchar(100) character set utf8mb4;

SET NAMES utf8mb4;

insert tmp2 values('befoređź’€after');
