6.3.1.3 '-T': Changing both TeX and PostScript encodings
........................................................
The option '-T ENC-FILE' is equivalent to '-p ENC-FILE -t ENC-FILE'. If
you make regular use of a private non-standard reencoding '-T' is
usually a better idea than the individual options, to avoid unexpected
inconsistencies in mapping otherwise. An example of when you might use
this option is a dingbats font: when you have a TeX encoding that is
designed to be used with a particular PostScript font.
