I have a ttf on my machine, 'Abilene'.

I used it in a page.
I can select eot, svg, ttf, and can publish without error.

If I select woff in tools / font / @font-face options,
wysiwyg builder crashes as soon as I start the publish.

any other font type does not cause a crash.

Iphone 7 does not see the correct font.
android tablet does not see the correct font.

my windows machine of course sees the font
since it is installed on the machine.

I think I am doing it right,
since one machine does see it correctly.
another win 10 pc also sees the font correctly.

Obviously something I do not understand.

Ideas?

This means that the fonts cannot be automatically converted, the format is unknown for WWB.
In that case you will have to convert it manually to woff.

This free tool works good:
