--------------------------------------
Summary: Implement UTF-8 encoding that doesn't use CharsetEncoder
Key: LOG4J2-1873
URL: https://issues.apache.org/jira/browse/LOG4J2-1873
Project: Log4j 2
Issue Type: Improvement
Reporter: Roman Leventov
CharsetEncoder accepts only CharBuffers, and for the sake of being entirely
garbage-free we don't want to use CharBuffer.wrap(stringBuilder), when encoding
an event.
That forces us to make additional data copy from StringBuilder to a
thread-local CharBuffer.
This could be avoided by implementing UTF-8 encoding logic in log4j-core
itself, and not using CharsetEncoder.
This issue is specifically about UTF-8 because it is used predominantly and
it's relatively easy to implement. There are also likely some open-source
Apache 2-compatible implementations in Java out there already that we could
just copy and adapt.
