Hello!
I’ve recently started encountering an error when an app (recognize) tried to insert a tag with Thai characters into my UTF-8 encoded Postgres DB: พระที่นั่งอาภรณ์ภิโมกข์ปราสาท. I initially opened this issue in the app’s repo, but it’s actually nextcloud related as I also cannot manually tag a file with the mentionned tag and get the same error message.
The error message is:
Doctrine\DBAL\Exception\DriverException: An exception occurred while executing a query: SQLSTATE[22021]: Character not in repertoire: 7 ERROR: invalid byte sequence for encoding "UTF8": 0xe0 CONTEXT: unnamed portal parameter $1
I checked that the Postgres db was indeed set to UTF-8 which it is,
nextclouddb=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | ICU Locale | Locale Provider | Access privileges
-------------+-----------+-----------+---------+-------+------------+-----------------+-------------------------
nextclouddb | nextcloud | UTF8 | C | C | | libc | nextcloud=CTc/nextcloud+
| | | | | | | root=CTc/nextcloud
Browsing a little bit through issues and stackoverflow threads, it would seem that the collate setting of the db could be the culprit here? What would be the course of action to address this?
Thanks for any help!
