   > @wForget, it's strange. I just applied the below patch to test your case 
on Velox side ([1.2.0 velox 
branch](https://github.com/oap-project/velox/commits/gluten-1.2.0)), the test 
passed.

   Using regular string instead of raw string can reproduce this issue. It also 
occurs on the main branch. I found Presto also allows control characters, like 
Spark. We may have to change simdjson's code to fix this issue. But not sure 
whether it is acceptable. See Velox PR: 
https://github.com/facebookincubator/velox/pull/11433
