> We could do the same in parquet-rs if we were willing to have a truncated
max statistic that's 1 byte larger than requested (which seems ok to me as long
as it's communicated that the truncation is a best effort, just like with page
and row group sizes).
This seems fine with me
Another approach might be to fallback to a one fewer characters if
incrementing the truncated character at `T` bytes would increase past `T` due
to promotion.
maybe something like
```rust
if let Some(incremented) = increment_utf8(input) {
if incremented.len() > max_len {
increment_utf8(remove_last_char(input))
}
}
```
