Description of problem: Unicode added Bitcoin sign (₿) in June 2017, and Microsoft gave update package to make Windows 10 support this sign, thus this sign become available in Arial, Calibri, Cambria, Consolas, Courier New, Microsoft Sans Serif, Segoe UI, Tahoma and Times New Roman. So I hope this sign become available in Liberation fonts as well. Additional info:
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
I, unfortunately, duplicated this request at https://pagure.io/liberation-fonts/issue/20. Anyway, this is solved in the version 2.00.4 of the fonts.
