Environment: Github Actions
Dart SDK: version 3.2.5, stable
OS: Windows

Steps to reproduce

• Create a folder that starts with u in the test folder. e.g utils so it looks something like test/utils/my_test.dart
  • Or create a test file that starts with u. e.g unsupported_throwables_test.dart
• Run a test on windows-latest with GH actions

dart test -p chrome --test-randomize-ordering-seed=random --chain-stack-traces
# or
dart test -p vm  --test-randomize-ordering-seed=random --chain-stack-traces

• Receive error:

/C:/Users/runneradmin/AppData/Local/Temp/dart_test_2615570/runInBrowser.dart:8:61:
Error: An escape sequence starting with '\u' must be followed by 4 hexadecimal digits.
          dom.window.console.log('Startup for test path test\unsupported_throwables_test.dart');

or

This appears like an issue in the test runner, but I'm not certain. Transferring to the test repo for additional triage

I would not expect this to repro with -p vm, but there is a clear problem with -p chrome.

@buenaflor - I have published a version with a fix for this issue - you should be able to get unblocked with a dart pub upgrade.
