Unicode 物件與編解碼器¶
Unicode 物件¶
Since the implementation of PEP 393 in Python 3.3, Unicode objects internally use a variety of representations, in order to allow handling the complete range of Unicode characters while staying memory efficient. There are special cases for strings where all code points are below 128, 256, or 65536; otherwise, code points must be below 1114112 (which is the full Unicode range).
UTF-8 表示法會在需要時建立並快取在 Unicode 物件中。
備註
自 Python 3.12 起，已移除 Py_UNICODE 表示法，並標示為已棄用的 API。更多資訊請參閱 PEP 623。
Unicode 型別¶
這些是 Python 中用於 Unicode 實作的基本 Unicode 物件型別：
-
PyTypeObject PyUnicode_Type¶
- 為 穩定 ABI 的一部分.
This instance of
PyTypeObjectrepresents the Python Unicode type. It is exposed to Python code asstr.
-
PyTypeObject PyUnicodeIter_Type¶
- 為 穩定 ABI 的一部分.
This instance of
PyTypeObjectrepresents the Python Unicode iterator type. It is used to iterate over Unicode string objects.
