Revert Python 3 UFO file to older version

[mistermunn]

Long story short, I had a few UFO files get opened and converted to Python 3 in the Robofont 3.2 beta. Not knowing they wouldn't be backward compatible, I've saved them. Now I need to open them in an older version of Robofont and cannot.

Does anyone have a way/technique for reverting these files back to Python 2 so I can continue to work on them?

@frederik and @gferreira Thank you so much for both of your insights. I'm relatively new to UFOs and Python, and appreciate any corrections. I chalk them up as guidance on my journey to becoming educated through my missteps.

File > Save As… will open a dialog where you can choose the desired UFO version:

ps. @mistermunn I’ve made a small edit to your 2nd post: “Python 3 UFOs” → UFO3s. (Python3 and UFO3 are very different things, they just happened to be introduced together to RoboFont in v3)

Just use Save As and pick UFO2 as format. Your roundtrip to vfb is a really bad solution. good luck

SOLVED! (Kind of)

I opened my Python 3 UFOs UFO3s in Robofont 3.2 Trial beta. Exported the VFB. Then ran that file through the vfb2ufo converter in Terminal and got a bare-necessities UFO out fo that. The new UFO I could actually open in Robofont 1.8 (Thanks, Frederik!). It's not a perfect solution, but it preserves my work about 90%.
