Character to glyph mapping bulk edit

FontCreator - Font Editor FontCreator - Support

Hello,

I need to move a bunch of glyphs from one Unicode block to another, i.e. change CMAP table for such amount of glyphs that makes it painful to go through each one individually and do the clicking with mouse. Is there way to edit the table values directly, or export & import it?

Thanks,
Jan

  1. Sort the font in Unicode order from the Tools menu
  2. Insert Characters, and add empty glyphs with the new Unicode mappings that you need
  3. Copy the glyphs that you need to move
  4. Select the new empty glyphs
  5. Edit menu paste special, and overwrite the existing mappings.
  6. Delete the old glyphs that are now unmapped

That creates glyphs with new IDs. I want to keep the same glyph IDs so that substitutions and everything else works as is.

OpenType Features don’t use Glyph IDs, they use Glyph names.

If you really need to keep the glyph IDs, then copy the code points from the newly added glyphs over the existing glyph outlines, using paste special, but only the code points.

In general the actual glyphs are used, but when compiling an OpenType layout feature script, the glyph names are used to find the glyphs.

To keep the same glyphs, this might slightly different approach should work:

  1. Sort the font in Unicode order from the Tools menu
  2. Insert Characters, and add the selection of codepoints
  3. Copy these new characters to the clipboard
  4. Select the original glyphs
  5. Edit menu paste special, to only copy the codepoints. Ensure you have selected “overrule same codepoints”.
  6. Delete the newly added characters that are now unmapped
