Re: [Freefont-bugs] Freefont bug: Incorrect character for U+240E SYMBOL FOR SHIFT OUT

[Steve White]

Hi Ian,

This problem isn't present in recent builds.  I'll send you a link.

Don't hesitate to file a bug report (preferably at
https://savannah.gnu.org/bugs/?group=freefont) if you see any further
issues!

Thanks!
