searching for Persian string in MySQL using laravel elequent

Question

In my laravel in order to search in products title column I use the following code:

$products->where('title', 'like', '%' . $request->title . '%');

the title column is a string column and data stored in it are in Persian. Also, the database collation is UTF8_general_ci. however, when I search something some titles are found and some aren't. I need the result to find every product which contains the $request->title in their title columns.

can you help me?

Answer 1

Change Collation UTF8_general_ci to latin1_swedish_ci

Collations have these general characteristics:

Two different character sets cannot have the same collation.

Each character set has one collation that is the default collation. For example, the default collation for latin1 is latin1_swedish_ci. The output for SHOW CHARACTER SET indicates which collation is the default for each displayed character set.

There is a convention for collation names: They start with the name of the character set with which they are associated, they usually include a language name, and they end with _ci (case insensitive), _cs (case sensitive), or _bin (binary).

In cases where a character set has multiple collations, it might not be clear which collation is most suitable for a given application. To avoid choosing the wrong collation, it can be helpful to perform some comparisons with representative data values to make sure that a given collation sorts values the way you expect.
