[🐛 Bug]: Error occurs if path contains multibyte characters

[matsuda-dcom]

What happened?

I noticed one day that my Jenkins job was failing.
I am writing tests for a web application with selenium using C#.
new ChromeDriver() fails if the path of the project file being tested contains multi-byte characters.
As far as I remember, no errors occurred in ver4.10.0.
The test passes by removing multibyte characters from the path.

How can we reproduce the issue?

Write and execute test code in a file whose path contains multibyte characters.

ChromeOptions options = new ChromeOptions();
var driver = new ChromeDriver(service, options);

Relevant log output

@bonigarcia does this look like it is output from the manager, (i.e., not the bindings)? Are there unit tests for these characters?

[bonigarcia]

Similar issues were reported in the past. When that happened, I tested the Rust side with a custom cache path with non-ASCII characters, and the Rust side worked as expected. But those tests I did were manual, i.e., not included in an automated test. So, I have just included some parameterized automated tests about using paths with similar characters. The Windows build is failing in CI, but for other reasons. The new tests should work.

However, the reported problem comes from Rust. Unfortunately, the error message is not very informative due to a problem with the error message (solved here).

In summary, I don't know why this problem happens to @matsuda-dcom.

@matsuda-dcom: Can you please execute the following command from your shell and share the output here? Thanks

C:\ProgramData\Jenkins\.jenkins\workspace\テスト\システムテスト\MyProject\bin\Debug\net8.0\selenium-manager\windows\selenium-manager.exe --browser chrome --debug

I found the same issue on the web.
https://harostudio.co.kr/selenium-exception-nosuchdriverexception-%ED%95%B4%EA%B2%B0-%EB%B0%A9%EB%B2%95/
My case is Japanese, but this case is Hangul.

If I change the nuget version back to 4.10.0 the test passes.

MyProject.csproj
-    <PackageReference Include="Selenium.Support" Version="4.21.0" />
-    <PackageReference Include="Selenium.WebDriver" Version="4.21.0" />
+    <PackageReference Include="Selenium.Support" Version="4.10.0" />
+    <PackageReference Include="Selenium.WebDriver" Version="4.10.0" />

According to the command execution output, Selenium Manager seems to work as expected. So, I still do not understand why this error is happening.

@matsuda-dcom: Please turn on logging and re-run your code. Information on how to adjust logs for your language can be found in our Troubleshooting documentation.

Also, you can update your Selenium Manager binary to get a better error description. I mean, replace the following file:

C:\ProgramData\Jenkins.jenkins\workspace\テスト\システムテスト\MyProject\bin\Debug\net8.0\selenium-manager\windows\selenium-manager.exe

With the one downloaded from here: selenium-manager-windows (you need to uncompress that ZIP file and replace the previous EXE file). Thanks.
