To Reproduce

Steps

Not really sure. All I did was ran mqtt-cli-4.7.3-win (also mqtt-cli-4.7.5-win) executable mqtt-cli.exe and it gives the gibberish.

Reproducer code

Details

• Affected MQTT CLI version(s): mqtt-cli-4.7.3-win (also mqtt-cli-4.7.5-win) for sure. I didn't check others.
• Used JVM version:

java --version
openjdk 11.0.12 2021-07-20
OpenJDK Runtime Environment Microsoft-25199 (build 11.0.12+7)
OpenJDK 64-Bit Server VM Microsoft-25199 (build 11.0.12+7, mixed mode)

I got the same output as above.

I installed mqtt-cli version 4.8.2-win and os is win11.
Java version: openjdk 16.0.2 2021-07-20 OpenJDK Runtime Environment Temurin-16.0.2+7 (build 16.0.2+7) OpenJDK 64-Bit Server VM Temurin-16.0.2+7 (build 16.0.2+7, mixed mode, sharing)

does the issue persist when you reset your terminal to use utf8 encoding?

how to do that

on windows the command is described here, though if you are not on powershell, you will probably have to type chcp then press <Tab> to see the right completion (maybe .com? - dont remember off hand), and then a space, followed by the unicode code 65001. on powershell, chcp 65001 should work.

@alexanderankin Gave it a shot with PowerShell and got different results. Looks to be similar, but with a different character set.

However, if I right click on the folder (Explorer) and then select the option to "Open In Terminal" it opens up a PowerShell terminal and there's zero gibberish output when running it from that perspective. I have no idea what is different with the terminal offered in that way then what PowerShell or CMD.exe are doing on their own.
