I've used fyne a couple times, and it couldn't handle something very basic: it couldn't render glyphs outside the built-in font and optionally, exactly one custom font (FYNE_FONT). Which means you're screwed or at least severely crippled if you want to support any kind of user-created content for an international user base. This problem has been brought up a million times on the issue tracker, and I don't think it has meaningfully advanced: https://github.com/fyne-io/fyne/issues/2572#issuecomment-154...
