Summary: [C++][Gandiva] Optimise castVarchar(string, int) function
for single byte characters
Key: ARROW-7660
URL: https://issues.apache.org/jira/browse/ARROW-7660
Project: Apache Arrow
Issue Type: Task
Components: C++ - Gandiva
Reporter: Projjal Chanda
Assignee: Projjal Chanda
The current castVarchar function does byte by byte check for handling multibyte
characters. Since most of the time string consists of single byte characters
optimise it for that case and move to the slow path when multibyte characters
detected.
