You might also be able to just write out instructions. E.g. it seems clear that each glyph encodes 11 bits of information because there are 11 potential strokes in each glyph. The table says what stroke to apply when the bit is 00000000001, 00000000010, 00000000100, etc., so you can probably just write down 11 indicators of what the strokes mean and a copy of the actual bip39 list and a sentence or two saying "go through the word list and increment an 11 bit number every time you encounter a word. The glyphs are the words you need." Then you'll have everything you need to reconstruct your seed.
