This is a known problem. It's a shortcoming of the Solaris iconv.
Try setting LANG=en_US.UTF-8

It's the default encoding for the "C" locale. Essentially 7-bit ASCII, I
think.

I'd guess UnicodeToBytes.getDefaultEncoder() is responsible. If it fails
to find a default encoding class it will retry Class.forName() each time
it is called.
Normally you wouldn't see so many calls to getDefaultEncoder() though.
Typically it is used only when a new Writer instance is constructed.
