ByteYue opened a new pull request, #13671:
URL: https://github.com/apache/doris/pull/13671
# Proposed changes
Previous logic of reverse function might not be strong enough to handle
illegal character. For example, one one byte size character would be mistaken
as one utf-8 character which occupies more than one byte space. And
unfortunately exceeding the buffer space during future process.
Issue Number: close #xxx
## Problem summary
Truncate the copy process when detecting overflow memory accessing.
