Set buffer encoding when running activation script

[vinistock]

Motivation

We've been getting some errors in telemetry when transforming the activation hash into a JSON complaining that there's no conversion between ASCII-8BIT and UTF-8. Indeed, there's no way to convert the encodings properly, but I don't understand why the encoding is ASCII-8BIT to begin with.

I tried setting LANG=C, LC_ALL=C and changed a bunch of VS Code settings, but I'm still unable to reproduce the issue. I want to try forcing the Buffer encoding to be UTF-8 when running the activation script, in hopes that this will fix the issue.

Implementation

Started setting the encoding for the exec call.

Automated Tests

Adjusted our existing tests.

I'm working on a different approach that I believe will be more robust. Ignore this PR.
