Garbled error pop-up when using under Simplified Chinese Windows environment

Environment

• OS and version: Windows 10 22H2 19045.3448
• VS Code: 1.82.2
• C/C++ extension: 1.17.5
• OS and version of remote machine (if applicable):
• GDB / LLDB version: 8.2.1

Bug Summary and Steps to Reproduce

Bug Summary:

When attempting to start a debugging session, OpenOCD may return errors such as connection denied in localized language, for instance:

OpenOCD：
Open On-Chip Debugger 0.12.0+dev-01297-g909fd47f9 (2023-09-06-10:18)
Licensed under GNU GPL v2
Error: unable to open ftdi device with description 'Dual RS232-HS', serial '*' at bus location '*'

Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections

GDB：
The target is assumed to be little endian
./gdb.txt:6: Error in sourced command file:       
localhost:3333: 由于目标计算机积极拒绝，无法连接。
.
(gdb)

In these cases, cppdbg would report an error in a pop-up, but in wrong encoding, as shown in this screenshot:

(gdb)

Start by reproducing the error with the supplied Windows 10 Simplified Chinese environment and cppdbg/OpenOCD/GDB configuration, then trace how cppdbg presents debugger errors in the pop-up. Done means the localized connection-denied message is readable in the pop-up without regressing the debugger output.
