```python
import zarr
import numpy as np

z1 = zarr.open('a.zarr', mode='w', shape=(1), chunks=(1), dtype='U6')
z1[:] = 'foo'

z2 = zarr.open('a.zarr', mode='a')
z2.append(np.array(['barbar'], dtype='U6'))

z3 = zarr.open('a.zarr', mode='r')
print(z3[:])
```

It works fine and prints `['foo' 'barbar']`, and the encoding is `""dtype"": ""<U6""`:
```
$ cat a.zarr/.zarray 
{
    ""chunks"": [
        1
    ],
    ""compressor"": {
        ""blocksize"": 0,
        ""clevel"": 5,
        ""cname"": ""lz4"",
        ""id"": ""blosc"",
        ""shuffle"": 1
    },
    ""dtype"": ""<U6"",
    ""fill_value"": ""0"",
    ""filters"": null,
    ""order"": ""C"",
    ""shape"": [
        1
    ],
    ""zarr_format"": 2
}
