Expected Result

Hello
I don't know if I chose the right type of object (bug, discussion) please excuse me in advance.

First of all, thank you for your work, it's really great!

Sorry if my English isn't perfect, I'm using a translation.

I wanted to try updating my Vaultwarden from version 2024.6.2 to the latest 2025.12.1 (I know... why I waited so long... lack of time).

I wanted to keep it simple: a fresh install of Vaultwarden with a backup/import from the MariaDB backup, but I'm having a problem when I try to import it (character collapse issue). I've tried modifying it, but it doesn't change anything, or maybe I'm missing something.

I could really use a little help; that would be great.

Thank you!

MariaDB [(none)]> SELECT DEFAULT_CHARACTER_SET_NAME, DEFAULT_COLLATION_NAME FROM information_schema.SCHEMATA WHERE SCHEMA_NAME = "vaultwarden";
+----------------------------+------------------------+
| DEFAULT_CHARACTER_SET_NAME | DEFAULT_COLLATION_NAME |
+----------------------------+------------------------+
| utf8mb4 | utf8mb4_unicode_ci |
+----------------------------+------------------------+

Mix with utf8mb4_unicode_ci and utf8mb4_uca1400_ai_ci,
how do I modify all the tables?

When I try to import the dump, I get this error.:

CREATE TABLE `attachments` (
`id` char(36) NOT NULL,
`cipher_uuid` char(36) NOT NULL,
`file_name` text NOT NULL,
`file_size` bigint(20) NOT NULL,
`akey` text DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `cipher_uuid` (`cipher_uuid`),
CONSTRAINT `attachments_ibfk_1` FOREIGN KEY (`cipher_uuid`) REFERENCES `ciphers` (`uuid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci

ERROR 1005 (HY000) at line 104: Can't create table vaultwarden.attachments (errno: 150 "Foreign key constraint is incorrectly formed")

I tried modifying the charset and collapse settings, but I must have missed something.
