[Question] how to store Korean data to the database and display it correctly in the database

A multi-language web project requires Chinese, English, and Korean support. Chinese and English are successfully completed. Korean is under development ......, However, if a problem occurs, the Korean language stored in the database cannot be correctly displayed.

Because the customer does not need to use the Korean interface to operate the background, the charset is still gb2312, Which is tested at this time.
The input Korean data is displayed in the database as follows: & #51116; & #47308; & #48516; & #47448; with such garbled code, the background can smoothly read and display the data, however, the front-end cannot call database data.

Then I thought it could be a charset problem. Then I changed it to charset = EUC-KR. In the database, Chinese characters are garbled: "flat-force Qian Fu Nong" ("Other-signs" in Chinese). In this case, data can be normally called in the front and back ends.

So: I don't know how to store Korean data, so I 'd like to ask you here. Thank you.
