I just wondered, is it possible that the unicode codepoint which is assigned to the copyleft symbol might not be the correct codepoint?

See: https://www.fileformat.info/info/unicode/char/1f12f/index.htm
Good catch. Thank you
New release is out that includes a fix: https://github.com/rsms/inter/releases/tag/v3.11
