Codec lookup API¶

In the following functions, the encoding string is looked up converted to all lower-case characters, which makes encodings looked up through this mechanism effectively case-insensitive. If no codec is found, a KeyError is set and NULL returned.

PyObject*
PyCodec_Encoder
(const char
 *encoding
)
¶

Return value: New reference.

Get an encoder function for the given encoding.

PyObject*
PyCodec_Decoder
(const char
 *encoding
)
¶

Return value: New reference.

Get a decoder function for the given encoding.

PyObject*
PyCodec_IncrementalEncoder
(const char
 *encoding, const char
 *errors
)
¶

Return value: New reference.

Get an IncrementalEncoder object for the given encoding.

PyObject*
PyCodec_IncrementalDecoder
(const char
 *encoding, const char
 *errors
)
¶

Return value: New reference.

Get an IncrementalDecoder object for the given encoding.

PyObject*
PyCodec_StreamReader
(const char
 *encoding,
PyObject
 *stream, const char
 *errors
)
¶

Return value: New reference.

Get a StreamReader factory function for the given encoding.

PyObject*

Was it clear so far?

PyCodec_StreamWriter
(const char
 *encoding,
PyObject
 *stream, const char
 *errors
)
¶

Return value: New reference.

Get a StreamWriter factory function for the given encoding.

Registry API for Unicode encoding error handlers¶

int
PyCodec_RegisterError
(const char
 *name,
PyObject
 *error
)
¶

Register the error handling callback function error under the given name. This callback function will be called by a codec when it encounters unencodable characters/undecodable bytes and name is specified as the error parameter in the call to the encode/decode function.

The callback gets a single argument, an instance of UnicodeEncodeError, UnicodeDecodeError or UnicodeTranslateError that holds information about the problematic sequence of characters or bytes and their offset in the original string (see Unicode Exception Objects for functions to extract this information). The callback must either raise the given exception, or return a two-item tuple containing the replacement for the problematic sequence, and an integer giving the offset in the original string at which encoding/decoding should be resumed.

Return 0 on success, -1 on error.

PyObject*
PyCodec_LookupError
(const char
 *name
)
¶

Return value: New reference.

Lookup the error handling callback function registered under name. As a special case NULL can be passed, in which case the error handling callback for 'strict? will be returned.

PyObject*
PyCodec_StrictErrors
(
PyObject
 *exc
)
¶

Return value: Always NULL.

Raise exc as an exception.

PyObject*
PyCodec_IgnoreErrors
(
PyObject
 *exc
)
¶

Return value: New reference.

Ignore the unicode error, skipping the faulty input.

PyObject*
PyCodec_ReplaceErrors
(
PyObject
 *exc
)
¶

Return value: New reference.

Replace the unicode encode error with ? or U+FFFD.

PyObject*
PyCodec_XMLCharRefReplaceErrors
(
PyObject
 *exc
)
¶

Return value: New reference.

Replace the unicode encode error with XML character references.

PyObject*
PyCodec_BackslashReplaceErrors
(
PyObject
 *exc
)
¶

Return value: New reference.

Replace the unicode encode error with backslash escapes (\x, \u and \U).

PyObject*
PyCodec_NameReplaceErrors
(
PyObject
 *exc
)
¶

Return value: New reference.

Replace the unicode encode error with \N{...} escapes.
