zhichao-li created SPARK-9238:
---------------------------------
Summary: two extra useless entries for bytesOfCodePointInUTF8
Key: SPARK-9238
URL: https://issues.apache.org/jira/browse/SPARK-9238
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: zhichao-li
Priority: Trivial
Only a trial thing, not sure if I understand correctly or not but I guess only
2 entries in bytesOfCodePointInUTF8 for the case of 6 bytes codepoint(1111110x)
is enough.
Details can be found from https://en.wikipedia.org/wiki/UTF-8 in "Description"
section.
