# Sample script to convert legacy cmap subtables to format-4
# subtables. Note that this is rarely what one needs. You
# probably need to just drop the legacy subtables if the font
# already has a format-4 subtable.
# Other times, you would need to convert a non-Unicode cmap
# legacy subtable to a Unicode one. In those cases, use the
# getEncoding() of subtable and use that encoding to map the
# characters to Unicode... TODO: Extend this script to do that.
