I need advice about a problem that i can't figure out how to solve it.
I sent a font to a site and they replied to me they cannot accept the file because:
Process start (TTF file)
OTS ERROR::CFF: Failed validating charstring set 0
OTS ERROR::CFF : failed to parse table
Failed to sanitise file!
Font failed OT Sanitizer check
Issues in the font file:
CFF table error, failed to parse table
Issues in the font file that can be fixed using OTScrubber :
There was a problem with the structure of the 'CFF ' table"
They find some kind of problem with CFF table. How can i scan a file to find this type of problem? and how can ai solve it?
