The Java JDK 1.0.2 implementation from Javasoft truncates everything to
ISO-8859-1 when drawing strings, because the implementation couldn't
handle anything else. This is mentioned in the Java 1.0.2 API
specification, which is available both at Javasoft's web site
( under the "Developer" section, and as a book.
The file I/O stuff that reads and writes UTF-8 work correctly, though.

This will be fixed in the JDK 1.1 release from Javasoft. Also, Netscape
Navigator 3.0 does a much better job now. It handles most of the scripts
the host OS supports now. The Mac version messes up if you have both
Chinese and Japanese installed; it doesn't handle the non-Japanese
Chinese characters correctly. Still, it handles Latin, Cyrillic, Symbols,
Japanese, and the compatibility area pretty well.

It's hard to implement Unicode rendering on platforms that don't support
Unicode directly, so it's taking a while for vendors to implement this
