Unicode mapping for SimSun font after split

FontCreator - Font Editor FontCreator - Support
1

After I split the simsun.ttc font file with FontCreator 6.0, I can view the three individual fonts - but the unicode mappings seem to be (mostly) empty.
Is there a way to import the unicode mappings from the TTC file into the generated TTF files?

Thanks!

The .ttc export feature ensures all available mappings are included in the fonts.
