Is the version of Charset you're using 0.3.1 or higher?

Come to think of it, I think that's the problem. I thought what was on curseforge was the latest. Looks like that hasn't been updated in ages. Could you point me in the location of the most recent version of charset please and thank you? Then you can go ahead and close this.

This is with Charset-0.3.0-pre15

nevermind found it, closing

http://charset.asie.pl/ for future reference. I do not use CurseForge, although Vazkii did for a while when he was maintaining the mod.
