Hey Spencer.
Anyways, this seems like an all-too-common "assume everything is 7-bit ASCII" error at some point between where the text is shown in mini and where it is fed into ChucK. Notably it works fine in command line chuck, which I don't think was explicitly mentioned.
Also not mentioned here and what did show up when the same issue was found in a workshop I gave was that closing the block comment with a ";" made it work as expected. I believe that it's limited to the Mini on OSX and only affects block comments at the start of the file. It may or may not be limited to files written in the Mini on that platform, it might even be limited to files/buffers written in that session, for all I know. Lacking a Mac here I don't dare send any example code as I can't verify it here and now. Yours, Kas.
