Comment(by charris):

 This is peculiar, it is only S3 that causes problems:


 {{{
 In [6]: array(arr, dtype="|S4")
 Out[6]:
 array(['1', '12', '123', '1234', '1234'],
       dtype='|S4')

 In [7]: array(arr, dtype="|S3")
 Out[7]:
 array(['1', '\x00\x001', '2', '\x0012', '3'],
       dtype='|S3')

 In [8]: array(arr, dtype="|S2")
 Out[8]:
 array(['1', '12', '12', '12', '12'],
       dtype='|S2')

 In [9]: array(arr, dtype="|S1")
 Out[9]:
 array(['1', '1', '1', '1', '1'],
       dtype='|S1')

 }}}
