What did you do?

  1. Download arcade_n.ttf from http://9031.com/fonts/#arcade https://www.dafont.com/arcade-ya.font
  2. Parse it with opentype.Parse

What did you expect to see?

No error

What did you see instead?

Error sfnt: invalid OS/2 table from opentype.Parse

At lease, this can be parsed with github.com/golang/freetype/truetype. I'm not sure which the font or the opentype library is to blame.

Sorry but Arcade-Regular.ttf was an old version and seems no longer available in the website. Let me close this.
