Understanding PostScript font conversion issues
When converting a font using Fontographer 4.1 from Macromedia, choose File➛GenerateFontFile. In the dialog box, select Advanced and in the Encoding section, select Adobe Standard. Do not change any other options.
If you used Fontographer 4.1 from Macromedia, check the font’s KernPair value. There is a problem in Fontographer 4.1 in which it uses incorrect KernPair values when converting some TTF fonts. After converting a font with Fontographer and installing the font using fontutils, go to the font metrics directory and use the UNIX grep utility to search for the string KPX in the font’s AFM file.
grep -c KPX mynewfont.afm
Open the .afm file in a text editor, search for the StartKernPairs variable, and check the value. If the StartKernPairs number is not the same as the number displayed using the grep utility, replace the number with the one displayed from the grep command.
