Brief problem description

When using b2.exe to build other boost components, because b2 needs to use the Windows api GetTempPathA to find the temporary directory, and the username in %TMP% contains non-ASCII characters, this leads to the failure of writing temporary files to this directory, As a result, subsequent reading of this temporary file fa

Related vcpkg issue: microsoft/vcpkg#24473

Steps to reproduce the issue

1. Create a account which name contains non-ASCII characters.
2. Build b2.
3. Build other boost components such as boost-regex.

Actual behavior summary

Failed to read temporary file.

Expected behavior summary

Other components should be built successfully.

Is there any way to circumvent this problem temporarily?

Thanks,

In the short term I believe you can set the TEMP end var in your user environment to redirect where that goes. I.e. make it go to a path that doesn't have the unicode chars. In the long term I'm investigating fixing this problem in a future release. But unicode in Windows is filled with landmines. So it's not going to be easy.
