U+1F844
- Is duplicate of Feature #31921: Changes to properly support 4 byte characters (emoji) when database is MySQL added
- Status changed from New to Closed
- Resolution set to Duplicate
Sometimes (especially when using an older database with MySQL), the underlying database only supports the storage of up to three-byte UTF-8 characters. However, some characters (such as the LEFTWARDS HEAVY ARROW) require four bytes of storage.
To be able to enter those characters, you would need to upgrade your existing database to support 4 bute characters. This means you need to change the collation of the rows from `utf8` to `utf8mb4`. To be ablt to do that, you also need to use row_format = DYNAMIC and the Baracuda file format).
Please see #31921 and http://blog.andriylesyuk.com/4-byte-utf-8-problem-in-redmine-and-how-to-fix-it/ for some details on how to migrate your existing database. Before performing these changes, please make sure that you have a full and working backup of your database so that you can revert to that backup in case anything goes wrong.
