This function is used to load a font into memory for later use with PDF_setfont()
This function is the replacement for the depracated PDF_find_font()
And also here is the 'core font' list, for PDF files, these do not need to be embeded:
- Courier
- Courier-Bold
- Courier-Oblique
- Courier-BoldOblique
- Helvetica
- Helvetica-Bold
- Helvetica-Oblique
- Helvetica-BoldOblique
- Times-Roman
- Times-Bold
- Times-Italic
- Times-BoldItalic
- Symbol
- ZapfDingbats
And with encodings i have found its best to use iso8859-1 for english with a $ for currency.
