+  * :func:`!PyUnicode_Encode`
+  * :func:`!PyUnicode_EncodeASCII`
+  * :func:`!PyUnicode_EncodeLatin1`
+  * :func:`!PyUnicode_EncodeUTF7`
+  * :func:`!PyUnicode_EncodeUTF8`
+  * :func:`!PyUnicode_EncodeUTF16`
+  * :func:`!PyUnicode_EncodeUTF32`
+  * :func:`!PyUnicode_EncodeUnicodeEscape`
+  * :func:`!PyUnicode_EncodeRawUnicodeEscape`
+  * :func:`!PyUnicode_EncodeCharmap`
+  * :func:`!PyUnicode_TranslateCharmap`
+  * :func:`!PyUnicode_EncodeDecimal`
+  * :func:`!PyUnicode_TransformDecimalToASCII`
