### Benchmark mojimoji vs unicodedata and zenhan

Source: https://pypi.org/project/mojimoji

Benchmark results show the performance of mojimoji.zen_to_han compared to unicodedata.normalize('NFKC', s) and zenhan.z2h(s) for converting a large string of full-width characters to half-width. The benchmarks are run using IPython's %time magic command.

```python
import mojimoji
s = 'ＡＢＣＤＥＦＧ０１２３４５' * 10

%time for n in range(1000000): mojimoji.zen_to_han(s)
```

```python
%time for n in range(1000000): unicodedata.normalize('NFKC', s)
```

```python
%time for n in range(1000000): zenhan.z2h(s)
```

### Convert Hankaku to Zenkaku Characters

Source: https://pypi.org/project/mojimoji

Use the `han_to_zen` function to convert half-width Japanese characters to full-width. Options `kana`, `digit`, and `ascii` can be set to `False` to disable conversion for specific character types.

```python
import mojimoji
print(mojimoji.han_to_zen('ｱｲｳabc012'))
```

```python
print(mojimoji.han_to_zen('ｱｲｳabc012', kana=False))
```

```python
print(mojimoji.han_to_zen('ｱｲｳabc012', digit=False))
```

```python
print(mojimoji.han_to_zen('ｱｲｳabc012', ascii=False))
```

```

```python

```

```python
print(mojimoji.zen_to_han('アイウａｂｃ０１２', digit=False))
```
