What encodings can't PS preserve, and why?

Utf-8. To be more specific: everything non ISO Latin-1 is a problem for the PS print routines in GNU Emacs:

These characters in the buffer can't be printed:
Ą, ą, Ł, €, „, Š, š, Ș, Ź, ź, Ż, Č, ł, Ž, ”, and more...
Click them to jump to the buffer position,
or C-u C-x = will give information about them.

Please don't mention PS Mule and BDF fonts! The reason why it fails lies in the PostScript fonts: they can only provide up to 256 glyphs. CID type PS fonts for use with CJK scripts can provide more glyphs. Right now there is no PostScript "fontset" defined that supports the planes defined in Unicode, not even for the first 64 K positions in the BMP, the Basic Multilingual Plane.

It is clever to use the operating system's knowledge.

There's something the technicians need to learn from the artists. If it isn't aesthetically pleasing, it's probably wrong.
