Question

I have MySQL db, db engine InnoDB, collation set to utf8-utf8_general_ci (also tried utf8_unicode_ci). I would like db to treat equaly č and c, ž and z, ć and c, š and s, đ and d.
E.g,

table1

-------------
id  | name
-------------
1   | mačka
2   | đemper
-------------

if I run query:
SELECT * FROM table1 WHERE name LIKE '%mac%'
or
SELECT * FROM table1 WHERE name LIKE '%mač%'
I will get the result:

-------------
id  | name
-------------
1   | mačka

Which is OK, that is exactly what I want.
But if run query:

SELECT * FROM table1 WHERE name LIKE '%de%'

I get zero results.

And if I run query:

SELECT * FROM table1 WHERE name LIKE '%đe%'

I will get:

-------------
id  | name
-------------
2   | đemper

This is not behaviour that i would want nor expect. I would like that both (last two queries) returned:

-------------
id  | name
-------------
2   | đemper

How can I accomplish this?
Any kind of help is appreciated, thanks in advance 🙂 !

This can’t be done without the use of regular expressions, as there is no collation in MySQL that considers đ equivalent to d.
