When running certain rails scripts in OSX' Terminal, I get warnings such as the following:unable to convert \xA9 from ASCII-8BIT to UTF-8 for tmp/cache/assets/CC7/4D0/sprockets%2Fd7d58761510113ba5435f0baba05573b, skippingI've added export LC_CTYPE=utf-8to my .bash_profile, but that did not fix anything. Apparently, these warnings don't matter, but I want to fix them. They're literally hundreds of them and they're a bit annoying.
