pstotext – Extract ASCII from PostScript and PDF
A Unix program that extracts ASCII text from PostScript and PDF (Acrobat) files. pstotext uses Ghostscript, but does a more careful job with kerned characters and nonstandard font encodings than Ghostscript's ps2ascii utility.
Pstotext is no longer held on CTAN; documentation and downloads are available from its home page.
