Is there a way to transliterate European accent characters only, but leave Chinese characters as it is?

My code is as follow:
```
from unidecode import unidecode

s = "中文字café"

output = unidecode(s)
print(output)
```
It outputs `Zhong Wen Zi cafe`. Can the function only transliterate European accent characters only, but leave Chinese characters as it is? 

Desired output: `中文字cafe`

Thanks.
