However, some characters doesn't work:
/venus /Omega /bulletoperator /middot /blacksquare

Why it doesn't work? Did I put it in wrong, or is it not implemented in
the font? The font I used is "NimbusMonoPS-Regular" font in Ghostscript,
which is aliased as "Courier".

Have you checked the font to see if it contains glyph descriptiosn
identified with those names ?

Since these are unusual glyphs, almost certainly the font doesn't
contain them.

It look like it doesn't include these names. (All of the other glyphs I
specified in the PCEncoding are working, though.)

Would you be able to tell me then what is the proper glyph names for PC
Encoding? If they are the glyphs that this font does not include, which
font does have it, and does Ghostscript include it? (And if not, should
Ghostscript include it?)

What do you mean by "PC encoding"?

If you want to see what glyph names a font has defined look in its
..AFM (Adobe Font Metrics) file

Well, there you go then.

As Rod says, what exactly do you mean by 'PC Encoding' ?

I have no clue. If you want to use those glyphs then it's up to you to
source a font which includes them.

> and does Ghostscript include it?

You say yourself that the font (not Ghostsceript, Ghostscript is not a
font) does not include these.

> (And if not, should Ghostscript include it?)

Fonts are not required to include every glyph shape known to mankind, so
no there is no reason why the fonts used by Ghostscript should include
them.

You can, of course, use a different font.

I mean the characters of IBM PC.

The page https://en.wikipedia.org/wiki/Code_page_437
lists corresponding Unicode code points (numeric values, in hex.)
Pages such as https://unicodemap.org/details/0x255D/index.html
give names, such as "Double Up and Left" for 0xBC ==> 0x255D.

I have a Type 3 font of Code Page 437. It just uses a fixed bitmap.
