    tf.raw_ops.UnicodeDecode(
        input,
        input_encoding,
        errors='replace',
        replacement_char=65533,
        replace_control_characters=False,

    )

The character codepoints for all strings are returned using a single vector
`char_values`, with strings expanded to characters in row-major order.

The `row_splits` tensor indicates where the codepoints for
each input string begin and end within the `char_values` tensor.
In particular, the values for the `i`th
string (in row-major order) are stored in the slice
`[row_splits[i]:row_splits[i+1]]`. Thus:

- `char_values[row_splits[i]+j]` is the Unicode codepoint for the `j`th character in the `i`th string (in row-major order).
- `row_splits[i+1] - row_splits[i]` is the number of characters in the `i`th string (in row-major order).

| ## Args ||
|---|---|
| `input` | A `Tensor` of type `string`. The text to be decoded. Can have any shape. Note that the output is flattened to a vector of char values. |
| `input_encoding` | A `string`. Text encoding of the input strings. This is any of the encodings supported by ICU ucnv algorithmic converters. Examples: `"UTF-16", "US ASCII", "UTF-8"`. |
| `errors` | An optional `string` from: `"strict", "replace", "ignore"`. Defaults to `"replace"`. Error handling policy when there is invalid formatting found in the input. The value of 'strict' will cause the operation to produce a InvalidArgument error on any invalid input formatting. A value of 'replace' (the default) will cause the operation to replace any invalid formatting in the input with the `replacement_char` codepoint. A value of 'ignore' will cause the operation to skip any invalid formatting in the input and produce no corresponding output character. |
| `replacement_char` | An optional `int`. Defaults to `65533`. The replacement character codepoint to be used in place of any invalid formatting in the input when `errors='replace'`. Any valid unicode codepoint may be used. The default value is the default unicode replacement character is 0xFFFD or U+65533.) |
| `replace_control_characters` | An optional `bool`. Defaults to `False`. Whether to replace the C0 control characters (00-1F) with the `replacement_char`. Default is false. |
| `Tsplits` | An optional [`tf.DType`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/dtypes/DType) from: `tf.int32, tf.int64`. Defaults to [`tf.int64`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf#int64). |
| `name` | A name for the operation (optional). |

<br />

<br />

| ## Returns ||
|---|---|
| A tuple of `Tensor` objects (row_splits, char_values). ||
| `row_splits` | A `Tensor` of type `Tsplits`. |
| `char_values` | A `Tensor` of type `int32`. |
