If you are using DX7 or older, you will need to update the emote column to support storing emotes in the database. (For more information, DX7 or older is using utf8mb3 encoding)

For example, after importing the sample app, you should run the SQL code below to change the emote column to utf8mb4 encoding.

ALTER TABLE `app_fd_efesa_store` 
CHANGE COLUMN `c_emote` `c_emote` LONGTEXT 
CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL DEFAULT NULL;
