### Build Troubleshooting

Here are tips for issues users have reported.

#### Internationalization

I didn't check that the tests pass or the scripts work if your language environment isn't English. So, no surprise I guess, a German user reported that three tests failed when running `sbt test` while the `LANG` was set to `de_DE.UTF-8`:

```
[info] Passed: Total 7, Failed 0, Errors 0, Passed 7
[error] Failed: Total 233, Failed 7, Errors 0, Passed 226
[error] Failed tests:
[error] progscala3.fp.combinators.PayrollSuite
[error] progscala3.fp.curry.TupledFuncSuite
[error] progscala3.dsls.payroll.PayrollSuite
[error] (Test / test) sbt.TestsFailedException: Tests unsuccessful
[error] Total time: 2 s, completed 31.07.2021, 16:56:39
```


Setting `export LANG="en_US.UTF-8"; sbt test` works. A PR for this is welcome ;) As an interim step, you could wrap this logic (or the more concise single command `LANG="en_US.UTF-8" sbt test`) in a script or just ignore the three failing tests.

## Feedback
