You must have a MySQL 8/MariaDB database with utf8md4 settings

Since this is not a risk-free operation it is necessary to back up the database before proceeding.

Connect to the database using mysql client

mysql -u root -p logicaldoc

Check the status of the charset settings are OK with the query below

 SHOW VARIABLES LIKE 'char%';

Execute the following SQL statements on the relevant field of the tables: ld_document, ld_version, ld_history

ALTER TABLE

    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
    COLLATE utf8mb4_unicode_ci;

ALTER TABLE
    ld_version
    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
    COLLATE utf8mb4_unicode_ci;


ALTER TABLE

    CHANGE ld_filename ld_filename
    VARCHAR(255)
    CHARACTER SET utf8mb4
