[extension] When the agent runs the terminal, non-English characters do not display correctly

What version of the VS Code extension are you using?

0.4.10

Which IDE are you using?

Cursor

What platform is your computer?

Darwin 24.1.0 arm64 arm

What steps can reproduce the bug?

I gave the agent a command to run the test code, and the test code titles are written in Korean.
When the agent executes the tests, the terminal shows the current running logs, but it seems that non-English characters are not displayed correctly.

What is the expected behavior?

The actual log should be displayed as follows.

$ bash -lc 'export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" && nvm use >/dev/null && npx playwright test tests/e2e/section.spec.ts'
[dotenv@17.2.2] injecting env (4) from tests/.env -- tip: 🛠️  run anywhere with `dotenvx run -- yourcommand`

Running 5 tests using 4 workers

What do you see instead?

The current log is displayed as follows.

$ bash -lc 'export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" && nvm use >/dev/null && npx playwright test tests/e2e/section.spec.ts'

Additional information

When reviewing the logs after the agent completes its work, they are displayed as expected.
It seems that the problem only occurs while the agent is running.
