`UNIHAN`_'s data is dispersed across multiple files in the format of::

U+3400 kCantonese jau1
U+3400 kDefinition (same as U+4E18 丘) hillock or mound
U+3400 kMandarin qiū
U+3401 kCantonese tim2
U+3401 kDefinition to lick; to taste, a mat, bamboo bark
U+3401 kHanyuPinyin 10019.020:tiàn
U+3401 kMandarin tiàn

``$ unihan-tabular`` will download Unihan.zip and build all files into a
single tabular friendly format.

CSV (default), ``$ unihan-tabular``::

char,ucn,kCantonese,kDefinition,kHanyuPinyin,kMandarin
㐀,U+3400,jau1,(same as U+4E18 丘) hillock or mound,,qiū
㐁,U+3401,tim2,"to lick; to taste, a mat, bamboo bark",10019.020:tiàn,tiàn

JSON, ``$ unihan-tabular -F json``:

.. code-block:: json

[
{
"char": "㐀",
"ucn": "U+3400",
"kCantonese": "jau1",
"kDefinition": "(same as U+4E18 丘) hillock or mound",
"kHanyuPinyin": null,
"kMandarin": "qiū"
},
{
"char": "㐁",
"ucn": "U+3401",
"kCantonese": "tim2",
"kDefinition": "to lick; to taste, a mat, bamboo bark",
"kHanyuPinyin": "10019.020:tiàn",
"kMandarin": "tiàn"
}
]

YAML ``$ unihan-tabular -F yaml``:

.. code-block:: yaml

- char: 㐀
kCantonese: jau1
