Open a pattern PDF in Illustrator and it used to greet you with a list of missing fonts, then quietly replace your symbols with empty boxes. Export settings > Vector Editing fixes that.
Tick Outline symbols and every symbol becomes an editable shape rather than text, so there's no font to go missing and nothing to substitute. Resize the chart, recolor it, pull it apart — the symbols stay exactly as you drew them. It costs about one percent on file size and prints identically.
For a file with no fonts in it at all, also pick Helvetica (standard) as your PDF font under Page Settings. Between the two, the document opens with no warnings whatsoever, and your titles and thread codes are still real text you can edit. One thing to know: Helvetica covers Latin characters only, so if your pattern has Cyrillic in it, stick with one of the other fonts — we'll warn you in the font picker either way.
If you'd rather keep symbols as text, Download font hands you the symbol font to install. It's built for one pattern specifically, so it won't match another pattern's chart.
Fonts embedded in your PDFs now also carry proper names instead of a different set of random numbers on every export — so if a program does ask about a font, the name it shows you is one you can actually look up.
Separately, Symbol size under Pattern Pages is now a real control. It sets how big symbols
are drawn inside each square, from 50% to 120%, so you can leave more of the color showing or
make a busy chart easier to read. The thread key keeps its own size, so your legend stays legible
whatever you do to the chart.
Happy stitching!
