This is NOT A BUG and not surprising at all. The font you are using is NOT
a Type 1 font - it is a rough font generated from a bitmap. If you try

	% gs
	GS>/F2 /Charter-Roman findfont 200 scalefont def
	GS>F2 setfont 0 0 moveto (AY) show
	GS>quit

you'll get lines smooth as silk.

Have a look in FONTMAP and see which fonts are true Type 1 (CHARTER, COURIER
UTOPIA in version 2.5.1). I suggest you use these fonts where possible.

The fact that xpsview gives you smooth lines simply shows that your X11 Server
has Type 1 fonts built in. The next version of GhostScript (2.6) will use these
fonts where available, until then use the Type 1 fonts in the GhostScript
distribution.
