There are illegal characters in the "license" string

I’m getting this message when I try to export a font called Runda Medium as a WOFF and WOFF2 file:

There are illegal characters in the “license” string.
Please fix this in the font info.

What does this mean?

FYI: I figured this out.

It may be worth posting your solution in case anyone else happens to search the same problem :slight_smile:

I am getting the same message. You said you figured it out. Would you please provide your solution?

Thanks in advance!

It means there are some control characters in the string.
