When viewing Quark's Information tab in a Chinese environment, extra spaces will be displayed.
If it's Quark's fault, I'll go to its issue tracker.

Hm. I think this has to do with assumptions on how JEI is breaking up lines and accommodating them with spaces. I'm not sure if there's a proper solution to this as JEI just doesn't expose enough information so I need to make guesses. I'll keep this open in the mean time.
