OMI fails with invalid character #767

I am running command on Linux to get Win32_ComputerSystemProduct from Windows. Expected Output:

If I store the output in a variable or any file, then some characters of xml data is changed. These characters are changed randomly.

This issue is reproducing on

Ubuntu 22.04
Ubuntu 24.04
Debian 11 (bullseye)
Debian 12 (bookworm)
Rocky Linux 8.9
Rocky Linux 9.3

Same command works on CentOS 7.

locale is set to en_US.UTF-8 on all OS.

Please help me in resolving this issue.

@vaibhavgulhane you use this in SCOM or Azure product? I don't see this scenario for supported products. can you try omicl ** > /tmp/yourresult.txt and then read the content from /tmp/yourresult.txt? from you description it seems be related to encoding of bash command.

@JumpingYang001 I am using this on Hyper-V. Redirecting to a file shows same behavior. Hexdump shows that characters are different every time. Below screenshots shows that string 32_Compu in Win32_ComputerSystem is changed with random characters. Changed characters are different in first and second screenshot:

Using stdbuf -o0 cmd > file resolves the issue.

glad to know you have work around, in fact, we don't have supported products that use that Linux omicli to query Windows now. :)
