Bug description

I create a chinese folder ,called 舍棉衣外套采购申请单青年美科技,and share with vechie，and it works well .so I login as vechie,first time it works well ,
when I refresh the browser some times，the folder changed as follows ：

At present, I am doing the nextcloud data migration test before, and another nextcloud of the same version shows correct, how to solve this phenomenon? The newly built nexcloud will happen.

If a folder name starting with Chinese is shared with another account, the folder name seen by the other account will be changed to (1) (2). But the shared account folder name is normal.

The nextcloud forum found a problem with the same phenomenon, but no solution, link:https://help.nextcloud.com/t/nextcloud19-0-0-share-folder-with-users-not-support-chinese-character/86769

This problem phenomenon is not regular, some display correct, some display abnormal。

Given that you're running such an old version (v19) it's really hard to say. In my limited testing in v28 I'm not able to reproduce this behavior.

At present, I am doing the nextcloud data migration test before, and another nextcloud of the same version shows correct, how to solve this phenomenon?

Well, what's different about the Servers and configurations? Or maybe the migration itself is introducing an unexpected variable?

Ideas:

• compare your configurations
• confirm both servers have the same PHP modules (namely intl)
• monitor your browser console and browser Network console to try to see what's happening
• monitor your web server logs to try to see what's happening
• set Nextcloud loglevel to 0 to try to see what's happening
• turn on Nextcloud debug mode to try to see what's happening

Unfortunately, this here isn't a general support channel. We can only address bugs in currently supported versions.

For general support you can use the Community Help Forum or make arrangements for Enterprise support (https://nextcloud.com/enterprise).

Thank you for your answer. The configurations of the two servers tested were the same.

As for the problem of the shared folder, I re-built the server locally for the test. I found in the database table oc_share that every time files were shared to other users, the display of other users' login to the Web side was correct, and when the interface was refreshed, only the shared files beginning with Chinese characters became (1) (2). The corresponding oc_share table contents are also (1) (2). Would like to ask if I should look up questions from database fields?

The tests that you have just re-built locally do not involve migration. Currently in the forum and search Microsoft search found the same phenomenon of the question, but there is no solution.

[joshtrichards]

Am I understanding correctly that this problem only occurs on your test server? Or is the original server also exhibiting the same behavior?

How are you migrating?

Currently in the forum and search Microsoft search found the same phenomenon of the question, but there is no solution.

In a maintained version of Nextcloud? I only saw v15 and v19 referenced, which are not maintained.

[Banqc0621]

For security reasons, the migrated new server uses the same version configuration as the original server httpd, mariadb,php, nextcloud. The original server does not have this problem, but the new server does.

Then I deployed and built nextcloud on my local computer with the same configuration as the migrated new server, and found that this problem occurred when I built nextcloud on my local computer for many times.

我是否正确理解此问题仅发生在您的测试服务器上？还是原始服务器也表现出相同的行为？

您是如何迁移的？

目前在论坛和搜索Microsoft搜索中发现了同样现象的问题，但目前还没有解决办法。

在Nextcloud的维护版本中？我只看到了引用的 v15 和 v19，它们没有得到维护。

Nextcloud的v15 和 v19，原服务器上搭建的并没有出现共享中文开头文件异常的问题。我想即使是版本的问题，应该也有解决办法，只是目前还没有找到

@Banqc0621 I can not reproduce this issue on any supported Nextcloud version. Please update to at least Nextcloud 27.

It could be a problem with the httpd version, here I found a post with the same problem：
