Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 467 comparisons, you can thus
expect the following amount of false-positive results:
  23.35 false positives, when considering a   5% risk acceptance (*, **, ***),
  4.67 false positives, when considering a   1% risk acceptance (**, ***),
  0.47 false positives, when considering a 0.1% risk acceptance (***)

The test doesn't pass on v20.x-staging, so it will need a manual backport:

$ ./node test/parallel/test-buffer-tostring-range.js
node:internal/errors:541
      throw error;
      ^
