I am facing problems with inserting Spanish characters from my application.
When I am inserting on the DB the characters are inserting properly, but when I am trying passing the same data in from the application, the data stored in the table isn't correct.
For example, when I insert directly on DB server:
CREATE TABLE prod_inns(`prod_name` varchar(100) COLLATE latin1_bin DEFAULT NULL)
insert into prod_inns values(Otoño);
I see this:
select * from prod_inns ;
+-------------+
| prod_name |
+-------------+
| Otoño |
+-------------+
delete FROM prod_inns ;
However, when I insert the same value from the application form, I see this instead:
select * from prod_inns ;
+-------------+
| prod_name |
+-------------+
| Otoño |
+-------------+
Here are my MySQL settings:
MySQL> show global variables like 'char%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
MySQL> show global variables like 'coll%';
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | latin1_swedish_ci |
| collation_database | latin1_swedish_ci |
| collation_server | latin1_swedish_ci |
+----------------------+-------------------+
3 rows in set (0.00 sec)
What's wrong with my settings? What should I do to store the data and read the data properly?
Note: I am using mysql-5.7.19

Don't use latin1, use utf8. You have "Mojibake" because the bytes in the client are utf8-encoded, yet you said they were latin1.
