I have Win8 and Java 1.8.0_25-b18, which also has no problem with ampersands. Firefox and IE both work.
There's probably not much I can do about this, since it seems to be a Java bug and I can't reproduce it. The outfit list isn't that useful of a feature anyway. If you want to know what to farm, the answer is dubious peppermints. (Everything else is worthless, rarely gets purchased, or both. Maybe plexi-pips if you have the outfit and a lot of patience.)
