Hi all,

To verify traditional Chinese characters processing with Logstash 5.4.1 on Windows, I did three simple tests on Windows 10 and Oracle JDK 1.8.0\_121.

Here are my three tests: [https://gist.github.com/desp0916/29ad9be45bffda3c6be5026cf076981a](https://gist.github.com/desp0916/29ad9be45bffda3c6be5026cf076981a).

First two test results are unexpected, but the third one is as expected. To my understanding, at least the result of test case #2 should be "network 網路" rather than "network ??", because the codec and charset are explicitly configured.

Could you help me to find the problem or solution?

Thanks in advance
