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).
