Wait, there may still be some minor issues. Let me verify them in UT. |

What changes were proposed in this pull request?
Even with the fix in #46824, the escape sequences (
\r,\n,\t, etc) are not handled properly. For example, when we uselog"\n", the StringContext interprets\nas a literal backslash\followed byninstead of a newline character. As a result, the bytes oflog"\n".messagebecomes[92, 110], instead of[10].This PR is to fix the issue by using the method StringContext.processEscapes in
LogStringContext.Why are the changes needed?
To ensure that escape sequences are properly processed in Spark logs
