[Bug]: Special character in ical url produce error when adding a new subscription #39892

Open Mat-DB opened 1 year ago

⚠️ This issue respects the following points: ⚠️

Bug description

When I add a new subscription in the calendar app I get the following error. The ical url is from my university. The problem is that one of my professors has a "ë" in his name which creates the problem. Also google calendar has a problem with this and just displays a "�" instead, which is fine for me everything is better than an error.

I have tested using the linuxserver.io docker image. I tried the mariadb docker container from linuxserver.io and I tried the offical postgresql docker container. Both do not work and generate the same error. I also tried sqlite which does work. Always tested on a clean install.

Steps to reproduce

  1. Open the calendar app.
  2. Add a new subscription to a ical url. In the description of at least one appointment is a "é".
  3. The error appears.

Expected behavior

Like google display a "�" or something similar instead of giving an error.

Thanks for your bug report :+1:

First, please make sure your sql server is configured properly for utf8mb4: https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/mysql_4byte_support.html. mysql.utf8mb4 => true is in your configuration file, we usually set it during installation if 4byte support is there.

Second, please connect to your sql server and check that the table oc_calendarobjects_props has the right collation: utf8mb4_bin

$CONFIG = array (
  'instanceid' => 'REMOVED',
  'passwordsalt' => 'REMOVED',
  'secret' => 'REMOVED',
  'trusted_domains' => 
  array (
    0 => 'localhost:450',
  ),
  'datadirectory' => '/data',
  'dbtype' => 'mysql',
  'version' => '27.0.0.8',
  'overwrite.cli.url' => 'https://localhost:450',
  'dbname' => 'nextcloud',
  'dbhost' => 'nextcloud-db',
  'dbport' => '',
  'dbtableprefix' => 'oc_',

  'memcache.local' => '\\OC\\Memcache\\APCu',
  'filelocking.enabled' => 'true',

);

So that is fine. How do I check this in the database, mariadb? Edit: I found it:

MariaDB [(none)]> SELECT      DEFAULT_CHARACTER_SET_NAME,      DEFAULT_COLLATION_NAME  FROM      INFORMATION_SCHEMA.SCHEMATA  WHERE      SCHEMA_NAME = 'nextcloud';
+----------------------------+------------------------+
| DEFAULT_CHARACTER_SET_NAME | DEFAULT_COLLATION_NAME |

| utf8mb4                    | utf8mb4_bin            |

Same error here, also all db-table with charset utf8mb4.

Also experiencing something similar on Nextcloud 27.1.1 with postgres 14 and an UTF8 db. The ical calendar contains an invalid character in some calendar items which causes an error.

Character not in repertoire: 7 ERROR: invalid byte sequence for encoding "UTF8": 0xe3 0x6f 0x20 Looks like we might need to encode the query before running it. Uff... encoding issues in PHP shudder

miaulalala commented 1 year ago

I will test this tomorrow - the idea is to create a new public calendar in NC and modify the public link token to contain one of those special chars that cause issues.

miaulalala commented 7 months ago

I can't reproduce, but as far as I can tell it's the calendarobjects_props table that is causing issues. There's code in the CalDavBackend that's supposed to replace chars that aren't supported

https://github.com/nextcloud/server/blob/ab6afe0111b25bd2d764bb807f086808ae7a5534/apps/dav/lib/CalDAV/CalDavBackend.php#L3096-L3098

But it might not be effective
