Server Info (please complete the following information):

OS: Debian GNU/Linux 11
Browser: Chome, Firefox
RMM Version: v0.15.8

Installation Method:

Standard
Docker

Agent Info (please complete the following information):

Agent version: v2.4.5
Agent OS: Win 10 21H1
OS Languge: Russian

Describe the bug

When executing command from Send command right click menu in WebUI the output you get is corrupted. Encoding issue?
When English is set as OS Language and the command is ran as user the issue is gone.

To Reproduce

Client OS's language should be Russian
In WebUI right click on a host => Send command
Run command that gives output in Russian (CMD or Powershell)
See encoding issues in command output

Expected behavior

Readable output in client OS language

Screenshots

Additional context

Same behavior is seen in Task/Script output.
MeshCentral's Remote Background Terminal works just fine.

When English is set as OS Language and the command is ran as user the issue is gone.
Changing browser language did not help the issue.

PS C:\Users\admin> Get-WinSystemLocale
LCID             Name             DisplayName
----             ----             -----------
1049             ru-RU            Russian (Russia)

TRMM server

root@test-trmm:~# cat /etc/default/locale
#  File generated by update-locale
LANG=en_US.UTF-8

Changing locale to ru_RU.utf8 (and other presented ru_ locales) changes nothing in command output.

you can add chcp 65001 > nul at bat scripts head

and [Console]::OutputEncoding = [System.Text.Encoding]::UTF8 at powershell scripts head

when you send commands to windows agent, you can use chcp 65001 > nul && you-command

These methods avoid changing the user's computer Settings.
