tf.experimental.numpy.unicode_

A unicode string.

tf.experimental.numpy.unicode_(
    *args, **kwargs
)

This type strips trailing null codepoints.

s = np.str_("abc\x00")
s
'abc'

Unlike the builtin str, this supports the :ref:python:bufferobjects, exposing its contents as UCS4:

m = memoryview(np.str_("abc"))
m.format
'3w'
m.tobytes()
b'a\x00\x00\x00b\x00\x00\x00c\x00\x00\x00'

:Character code: 'U' :Alias: numpy.unicode_
