I've been running VarAC on Linux Mint under Wine since before it was "supported" to do so, and it has worked well for me in general (in spite of the black TX text block, for which I found a work-around until that was fixed), *and* per the subject of this post the gestures have never worked for me. Of course, they work fine in Windows. I asked Irad what font was used, and have installed every emoticon font I can find in Wine, yet the gesture symbols do not display for me, even in the latest 6.6.13 version. I have verified that the symbols work properly in other Wine applications, and have even installed all those same fonts in Linux.
My question is: Do any of you who run VarAC in Linux have working gesture symbols? If so, what did you do to get them to work? If you did nothing specific to get them to work, but they "just worked" for you, please briefly describe what version of Linux you are running and what Wine installation process you used.
