Bug report
Kaltura uses a mix of latin1 and utf8 in its databases. The result is latin1 characters, stored inside utf8 tables, inside a latin1 database (!) Proof:
USE KALTURA; SET NAMES UTF8; SELECT id,name FROM entry;
See attach file 1
USE KALTURA; SET NAMES LATIN1; SELECT id,name FROM entry;
Linux distribution name and version: Ubuntu 16.04.6 LTS, Xenial

Hello @pkExec,
Thank you for your report. This is not actually a packaging/installation issue but rather, stems from how the schema is defined here: https://github.com/kaltura/server/blob/Propus-16.1.0/deployment/base/sql/01.kaltura_ce_tables.sql Since you were the one to find it, would you like to submit a pull request to the repo in question? That one, you'll be credited for your contribution.
Cheers,

Sorry I wasn't clear enough. The fix to the schema is easy enough, however this will break any existing databases, with garbled characters wherever non-latin language is used. This is how I noticed the problem.
If the schema is upgraded to use utf8 (I may get the time to submit the pull request for that), the packaging needs to use an upgrade script for the existing databases.
The upgrade script needs to run through all the text and varchar columns of all tables, and run a command similar to this:
UPDATE entry SET name = CONVERT(CONVERT(CONVERT(name USING latin1) USING binary) USING UTF8);
Hello @pkExec,
Indeed but these SQL alter/update scripts are also maintained in the server repo, see:
https://github.com/kaltura/server/tree/Propus-16.1.0/deployment/updates/sql
The postinst hook in the kaltura-base package then invokes these. See:
https://github.com/kaltura/platform-install-packages/blob/Propus-16.0.0/RPM/SPECS/kaltura-base.spec#L301
https://github.com/kaltura/platform-install-packages/blob/Propus-16.0.0/deb/kaltura-base/debian/postinst#L86
Cheers,
