terraform/output: unicode characters missing since 0.47.2

[sebhoss]

Describe the bug
I have a test that calls terraform.Output and that output contains a unicode character. After updating terratest from 0.47.1 to 0.47.2, those unicode characters are missing.

To Reproduce
Steps to reproduce the behavior, code snippets and examples which can be used to reproduce the issue.

output "id" {
  value = "söme chäräcter"
}

assert.Equal(t, "söme chäräcter", terraform.Output(t, options, "id"))

Expected behavior
The given output should be given as-is without removing unicode characters.

Nice to have

• See job logs at https://github.com/metio/terraform-provider-migadu/actions/runs/11130950971/job/30931610454?pr=205

Versions

• Terratest version: 0.47.2
• Environment details (Ubuntu 20.04, Windows 10, etc.): Ubuntu

Additional context

I think this is caused by #1445 which keeps printable ASCII chars only
