tf.strings.unicode_encode(
    input, output_encoding, errors='replace', replacement_char=65533, name=None
)

result[i1...iN] is the string formed by concatenating the Unicode codepoints input[1...iN, :], encoded using output_encoding.

Args
input	An N+1 dimensional potentially ragged integer tensor with shape [D1...DN, num_chars].
output_encoding	Unicode encoding that should be used to encode each codepoint sequence. Can be "UTF-8", "UTF-16-BE", or "UTF-32-BE".
errors	Specifies the response when an invalid codepoint is encountered (optional). One of: 'replace': Replace invalid codepoint with the replacement_char. (default) 'ignore': Skip invalid codepoints. 'strict': Raise an exception for any invalid codepoint.
replacement_char	The replacement character codepoint to be used in place of any invalid input when errors='replace'. Any valid unicode codepoint may be used. The default value is the default unicode replacement character which is 0xFFFD (U+65533).
name	A name for the operation (optional).

Returns
A N dimensional string tensor with shape [D1...DN].

Example:

>>> input = [[71, 246, 246, 100, 110, 105, 103, 104, 116], [128522]]
>>> unicode_encode(input, 'UTF-8')
