Apply normalize operation to UTF-8 string tensors.

Public Functions

explicit NormalizeUTF8(NormalizeForm normalize_form = NormalizeForm::kNfkc)

Constructor.

参数

normalize_form – [in] Valid values can be any of [NormalizeForm::kNone,NormalizeForm::kNfc, NormalizeForm::kNfkc, NormalizeForm::kNfd, NormalizeForm::kNfkd](default=NormalizeForm::kNfkc). See http://unicode.org/reports/tr15/ for details.

  • NormalizeForm.kNone, remain the input string tensor unchanged.

  • NormalizeForm.kNfc, normalizes with Normalization Form C.

  • NormalizeForm.kNfkc, normalizes with Normalization Form KC.

  • NormalizeForm.kNfd, normalizes with Normalization Form D.

  • NormalizeForm.kNfkd, normalizes with Normalization Form KD.
