Can I enter the actor's name in another language???

Only in Alternative Names option.

The main name must always be in roman characters. Or Romanized.
We should not use Cyrillic, Yiddish, Korean, Chinese, Japanese etc ...

NOTE
We do not support name translations. All names should be readable in English (diacritic are allowed).
If a person's name in their native language is not easily readable in English, it should be added as an alternative name.
