Blazemeter pip install error: "error C2220: the following warning is treated as an error"

[Guy Levin]

Using Windows 10.

1. python -m pip install --upgrade pip setuptools wheel
2. python -m pip install bzt

I get a long error trace, where the error is:

numpy\core\src\common\npy_cpu_dispatch.h(1): warning C4819: The file contains a character that cannot be represented in the current code page (1255). Save the file in Unicode format to prevent data loss

More of the log follows.

Thank you!
