PED and BOADICEA import/export problem when node IDs have non-alphanumeric symbols

The pedigree was constructed in ver 1.4RC.
Exporting and re-importing simple and phenotips JSON format worked well.
PED import failed with "Error importing pedigree: Multiple persons with the same ID [dad]".
BOADICEA import was successful, however blanks and " ' " were taken out of externalID filed ("Mom's mom" wass imported as Momsmom).

Update: actual issue is that both PED and BOADICEA IDs should be alphanumeric, but pedigree export (incorrectly) left apostrophes in place, and pedigree import incorrectly replaced them with spaces
