Private Use Area in U+E000..U+F8FF are supported.

Perhaps, it is better to mention utf-translate-cjk mode as this. 

* Encoding some characters as Unicode (UTF-8) is rejected by Emacs.

Emacs currently, by default, only supports the parts of the
BMP whose codepoints are in the ranges 0000-33ff and
e000-ffff.  This excludes CJK, Yi, Music, and Maths.

If you try to save a file containing characters with code
points outside this range, Emacs will suggest other
compatible coding systems.

By turing Utf-Translate-Cjk mode on, many more CJK
characters are included in the support.
