 11.8 VFtoVP: Virtual font to virtual property lists
 ===================================================
 
DONTPRINTYET  VFtoVP translates a virtual font metric (VF, ⇒(dvips)Virtual
 fonts) file and its accompanying TeX font metric (TFM, *noteDONTPRINTYET  VFtoVP translates a virtual font metric (VF, ⇒(dvips)Virtual
 fonts) file and its accompanying TeX font metric (TFM, ⇒
 (dvips)Metric files) file (as output by VPtoVF, for example) to
 "virtual property list format" (a list of parenthesized items describing
 the virtual font) that humans can edit or read.  This program is mostly
 used by people debugging virtual font utilities.  Synopsis:
 
      vftovp [OPTION]... VFNAME[.vf] [TFMNAME[.tfm] [VPLFILE[.vpl]]]
 
    The fonts VFNAME and TFMNAME (extended with '.vf' and '.tfm' if
 necessary) are searched for in the usual places (⇒
 (kpathsea)Supported file formats).  To see all the relevant paths, set
 the environment variable 'KPATHSEA_DEBUG' to '-1' before running the
 program.  If TFMNAME is not specified, VFNAME (without a trailing '.vf')
 is used.
 
    If VPLFILE (extended with '.vpl' if necessary) is not specified, the
 property list file is written to standard output.  The property list
 file can be converted back to VF and TFM format by the companion program
 VFtoVP (see the next section).
 
    The program accepts the following option, as well as the standard
 '-verbose', '-help' and '-version' (⇒Common options):
 '-charcode-format=TYPE'
      Output character codes in the PL file according to TYPE: either
      'octal' or 'ascii'.  Default is 'ascii' for letters and digits,
      octal for all other characters.  Exception: if the font's coding
      scheme starts with 'TeX math sy' or 'TeX math ex', all character
      codes are output in octal.
 
      In 'ascii' format, character codes that correspond to graphic
      characters, except for left and right parentheses, are output as a
      'C' followed by the single character: 'C K', for example.  In octal
      format, character codes are output as the letter 'O' followed by
      octal digits, as in 'O 113' for 'K'.
 
      'octal' format is useful for symbol and other non-alphabetic fonts,
      where using ASCII characters for the character codes is merely
      confusing.
