Yes, well...
It seems that my backslash (\), when used in RMVX, comes up as the symbol for japanese currency... So, what button should I press to get the backslash? I have tried quite a few options... Nearly all, and have perused the troubleshooting section for a while, but have found no help.
So, yeah...
I later learned that I was a total idiot, and that the difference in appearance doesn't matter... It is still the backslash...
