Hi there, I am working on a variable font and when I export as a variable font it says:
Problem compiling “GPOS” table
Subtable Overflow in lookup: 5 type: MarkToMarkAttachment
I have 704 glyphs in four masters including Latin(basic Latin to north-east European), numerals, marks, punctuations and very few Hanzi.
Latin extended letters are made with combining marks and basic letters all with correct anchors.
