-TEXSUBF:
Indicates the location of SDF files *.sfd for subfonts (Property Sheets->[Font2]).
Suppose the following is written in the font map file indicated by -ftt:
jbtm@UKS@ Gulim unicode
Then for the font corresponding to jbtmxx.tfm, the Windows TrueType Gulim is used under the unicode with the transformation of the character codes from the 8 bit code into 16 bit code according to UKS.sfd.
Here xx is usually two letters.
^r, ;, and \ can be used and have the same meanings as with -TEXPK:.
