Issues with semihosting with J-Link

[axelnxp]

This ticket is more a question than a bug report, I'm not sure what I'm trying to do is actually supported, so please let me know.

Describe the bug
I'm trying to setup semihosting with cortex-debug, using J-Link.
I came accross the following page: https://mcuoneclipse.com/2023/10/14/semihosting-with-vs-code-on-rp2040/
In this page, the author uses a custom library, on my side I'm using standard newlib-nano.
I re-used the launch configuration shared in this page to enable semihosting, so I added this:

"postLaunchCommands": [
                "monitor semihosting enable",
                "monitor semihosting ioclient 3",
            ],

I don't see any printf output in the debug consol or in the "gdb-server" terminal.
But, in my workspace folder, I see files are created and contain the printf output, those files have somehow corrupted names, eg:
:tt'$'\230\375\177
Also, I'm running gcov on the target, so when it dumps all the coverage results, the .gcda file name contains corrupted characters like the previous example.

I used Ozone to compare, and it correctly shows the printf/scanf in the terminal, and the .gcda file is named correctly.

Maybe worth to mention, I'm using VS Code in SSH from Windows to a Linux machine. The build/debug happens on the Linux machine.

Environment:

• Cortex-Debug Version 1.12.1
• OS: Linux Ubuntu 20.04 LTS
• GDB Version: 10.2.90.20210621
• Compiler Toolchain Version: GNU Arm Embedded Toolchain 10.3-2021.10
• J-Link version: V7.94b
