-------------------------------------------------------------
Gary, you are describing the different use case of sharing log files between
environments that use different encodings.
Fair enough, you need to tell the recipient what encoding the file is in.
In the use case I am describing, writing and reading is happening on the same
machine.
If you write UTF-8 bytes to the Console, the Console will interpret these bytes
as being in the platform encoding.
This works for English text because the platform encoding (I assume US-ASCII)
is a subset of UTF-8, so you cannot test this on your machine.
But for Japanese text, if you take UTF-8 bytes for "日本語" and you interpret
these bytes as MS932 (the platform encoding for Japanese Windows), you end up
with scrambled text.

> When I tried to log a Japanese string the output was scrambled in both the
> Console and a log file.
> For example,
> logger.warn("日本語テスト"); // (Japanese test)
> came out as
> 15:07:00.184 [main] WARN test.JapaneseTest - 譌･譛ｬ隱槭ユ繧ｹ繝?
