You 5# probably need to just drop the legacy subtables if the font 6# already has a format-4 subtable. 7# 8# Other times, you would need to convert a non-Unicode cmap 9# legacy subtable to a Unicode one. In those cases, use the 10# getEncoding() of subtable and use that encoding to map the 11# characters to Unicode...
