    TTFRemap -c file [-r] [-s | -u] <infile> <outfile>
Remaps the MS cmap of a font without removing any glyphs. Updates the OS/2
table according to first and last char of new cmap. The changes file consists
of lines of any of the following forms:

    uni_first, [uni_last,] uni_to
    g, gid_first, [gid_last,] uni_to
    n, name_first, [name_last,] uni_to
    d, uni_first[, uni_last]

where uni_first (gid_first) is the first of a range of Unicodes (glyph IDs)
in the source font, uni_last (gid_last) is the last of that range (if not
specified, default is same as uni_first (gid_last)), and uni_to
is the start of the sequential set of Unicodes that will be altered in the
output cmap so they map to the specified range. NOTE: Unicode values
should be in hex, glyph IDs are decimal. An initial d, deletes the range
from the output map (useful for -r).

    -p      Rename postscript names for shifted glyphs
    -r      Replace (copy the old cmap before mapping)
    -s      Convert to symbol encoding
    -u      Convert to UGL encoding
