bats: unknown test name

[adoyle-h]

When the bats runs in github action, it reports bats: unknown test name `$'test_l-2estr-5flen_-27G\303\251n\303\251ralit\303\251s-27''.
Actually the test title has some French and Chinese characters.

# bats: unknown test name `$'test_l-2estr-5flen_-27G\303\251n\303\251ralit\303\251s-27''
@test "l.str_len 'Généralités'" {
  run l.str_len 'Généralités'
  assert_success
  assert_output 14
}

# bats: unknown test name `$'test_l-2estr-5flen_-27\344\270\255\346\226\207-27''
@test "l.str_len '中文'" {
  run l.str_len '中文'
  assert_success
  assert_output 6
}

But it tests well on my MacOS. The "unknown test name" only appears in github action.
Can someone explain this? And how to fix the problem?
