Output Does Not Seem Correct on Japanese Characters

[gabehxd]

The outputted string is also not a valid filename which may or may not be in the intended scope?
Separator is also not working as intended.

Hi there @SunTheCourier. thank you for using this package. there are still some cases I maybe didn't' have support.
The separator might be a valid point, maybe i should apply the separator after normalize it.
are you using sluggy or sluggy unidecode?

[gabehxd]

I installed Sluggy Unideocde

[RubenMateus]

hi @SunTheCourier, can you check with the latest version?
I would recommend using SluggyUnidecode and use the overload:
{filename}.ToSlug("_");

Or just use the same overload you were using, should be correct now.
If it's still not correct, can you please provide a few test cases in a Pull request?
So I can check them out.
