### Is your feature request related to a problem or challenge?
Bit length for example doesn't support utf8view yet.
```
query error
select bit_length(arrow_cast('a', 'Utf8View'));

This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker

### Describe the solution you'd like
I hope we can support utf8view for all the string functions
