A. Coady updated ARROW-13522:
-----------------------------
Description:
{code:java}
import pyarrow as pa
import pyarrow.compute as pc
arr = pa.array(["ab", "ac"])
assert pc.utf8_ltrim(arr, characters="a").to_pylist() == ["b", ""]
assert pc.utf8_rtrim(arr, characters="b").to_pylist() == ["a", "a"]
{code}
Seems to go awry after the first match.
was:
```python
import pyarrow as pa
import pyarrow.compute as pc
arr = pa.array(["ab", "ac"])
assert pc.utf8_ltrim(arr, characters="a").to_pylist() == ["b", ""]
assert pc.utf8_rtrim(arr, characters="b").to_pylist() == ["a", "a"]
```
Seems to go awry after the first match.
> Regression with compute `utf8_*trim` functions.
