Topic: about font type questions

When I use GhostScript'command ps2pdf to convert ps files to pdf files,
it converts text to high-resolution bitmapped fonts rather than to embedded
outline fonts.Also it uses its own encoding but not the standard encoding
defined by Adobe.So it is difficult to extract text from the produced pdf
files.
I want to ask whether there are some rules when GhostScrip producing the
new pdf encoding which I can follow to extract the text.
Why ps files contain so many Type3 fonts?(I find it when I convert them to pdf)
How they are produced?
Are there any programs that can automatically produce
Type3 fonts?
If these font use their own encodings which are unknown to the public,
that means we can no longer extract the text written by these fonts.
