preview-latex: Font problems with Dvips

 
 5.1 Font problems with Dvips
 ============================
 
 Some fonts have been reported to produce wrong characters with
 preview-latex.  preview-latex calls Dvips by default with the option
 '-Pwww' in order to get scalable fonts for nice results.  If you are
 using antialiasing, however, the results might be sufficiently nice with
 bitmapped fonts, anyway.  You might try '-Ppdf' for another stab at
 scalable fonts, or other printer definitions.  Use
 
      'M-x customize-variable <RET> preview-fast-dvips-command <RET>'
 and
      'M-x customize-variable <RET> preview-dvips-command <RET>'
 in order to customize this.
 
    One particular problem is that several printer setup files (typically
 in a file called '/usr/share/texmf/dvips/config/config.pdf' if you are
 using the '-Ppdf' switch) contain the 'G' option for 'character
 shifting'.  This option will result in 'fi' being rendered as '#'
 (British Pounds sign) in several fonts, unless your version of Dvips has
 a long-standing bug in its implementation fixed (only very recent
 versions of Dvips have).
