5.2 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).
