Attachment encoding

bbc

Hi everybody!
Give me any advise, please. I’ve got a problem with attachment encoding in webapp if it names in ru_RU. When I’m trying to download attachment - the name of file looks like this - Ð_Ð»Ð°Ñ_Ñ_Ñ_.JPG.
In the webapp window it looks normal:

Locale is set to ru_RU.utf-8. Storages created with the same locale ru_RU.Utf-8 and works normal.

May be the problem because of database charset?

MariaDB [(none)]> SELECT * FROM INFORMATION_SCHEMA.SCHEMATA;
+--------------+--------------------+----------------------------+------------------------+----------+
| CATALOG_NAME | SCHEMA_NAME        | DEFAULT_CHARACTER_SET_NAME | DEFAULT_COLLATION_NAME | SQL_PATH |
+--------------+--------------------+----------------------------+------------------------+----------+
| def          | kopano             | utf8mb4                    | utf8mb4_general_ci     | NULL     |

Hi @bbc,

unfortunately the versions are quite old and we as Kopano do not have control over all the build dependencies. Can you request a trial download from https://kopano.com/downloads-demo/ and check if the same effect is the case there as well?

@fbartels Thanks for your answer!

@fbartels Thank you, i’ve installed 11 version. Tried upload/download attachments. There is no such problem.
Please, can you make it clear for me?
Kopano 8.7.0 is available for install in Ubuntu 20.04 repository. And also community continue developing 8 version, here is release 8.7.20 version https://documentation.kopano.io/kopano_changelog/kc.html
Is it just for supporting old versions and fix bugs?

I completely misunderstand with this release notes https://github.com/Kopano-dev/kopano-core/blob/master/RELNOTES.txt

Help, please? What version do you recommend for new installation 11 or 8.7?
Why there is so huge difference in version?
Thanks

Hi @bbc,

we are currently delivering two versions of the backend components to our customers. 8.7.x for the old installations and 9.x as part of Kopano One for the new generation of installations.

Version 11.0 is simply the current version for our master branch, which is the main development branch. Why the difference in version? Simply because we recently switched to semantic versioning for all our products, which means once a breaking change is introduced in one of the components, the mayor version needs to be increased. And just because a version has been tagged does not necessarily mean that we are happy enough with a certain release to deliver it to our paying customers.

If you are starting today I would recommend to go for Kopano One. I would generally not recommend to use the nightly builds for production setups, as they come without any guarantees or support.

@fbartels Thank you , it is clear to me now
