How can I enter data using non English (Bangla) language into this database table ?

As pointed out by @Tim you need to change the collation of your table/database/column to UTF-8. First check the collation of your database/table/column.

CHECK COLLATION:

How to check the collation of DATABASE:

SELECT
    default_character_set_name
FROM
    information_schema.SCHEMATA
WHERE
    schema_name = "YOUR_DATABASE_NAME";

How to check the collation of TABLE:

SELECT
    CCSA.character_set_name
FROM
    information_schema.`TABLES` T,
    information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA
WHERE
    CCSA.collation_name = T.table_collation
AND T.table_schema = "YOUR_DATABASE_NAME"
AND T.table_name = "YOUR_TABLE_NAME";

How to check the collation of a COLUMN:

SELECT
    character_set_name
FROM
    information_schema.`COLUMNS`
WHERE
    table_schema = "YOUR_DATABASE_NAME"
AND table_name = "YOUR_TABLE_NAME"
AND column_name = "YOUR_COLUMN_NAME";

Change COLLATION:

How to change database collation:

ALTER DATABASE YOUR_DATABASE_NAME CHARACTER SET utf8 COLLATE utf8_unicode_ci;

How to change table collation:

ALTER TABLE YOUR_TABLE_NAME CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

How to change column collation:

ALTER TABLE YOUR_TABLE_NAME MODIFY YOUR_COLUMN_NAME VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Example:

DROP TABLE IF EXISTS `sample_table`;
CREATE TABLE `sample_table` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `language` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO sample_table(name,language) VALUES('Ed Sheeran','English');
INSERT INTO sample_table(name,language) VALUES('আয়েশা খাতুন সুজানা','আমার সোনার বাংলা');

Look, the CHARSET used in the table definition is utf8. So, you can store unicode characters in the table.

Check whether the data inserted correctly or not.

SELECT * FROM sample_table;

Result:

| id |               name |         language |
|----|--------------------|------------------|
|  1 |         Ed Sheeran |          English |
|  2 |    আয়েশা খাতুন সুজানা |  আমার সোনার বাংলা |
