Defines a data type for variable-length UTF8 strings.
The value of the fill_value metadata key must be unicode string.
For example, the array metadata below specifies that the array contains variable-length byte strings:
{
"data_type": "string",
"fill_value": "foo",
"codecs": [{
"name": "vlen-utf8"
}],
}Currently, this data type is only compatible with the "vlen-utf8" codec.
