[Plugin: Auto Copyright] Missing Copyright Symbol

Nice plug-in! My plug-in is working, but it switched the “From” and “to” dates (displayed as “Copyright 2011-2010”). Not a big deal, I just switched the code around and now it displays fine.

My main problem is that it doesn’t display the little copyright symbol, just the missing character symbol. I’m using the Twenty-Ten WordPress theme, and I’m guessing the font just doesn’t recognize the character symbol.

I tried using the ascii html character code © but that broke the plug-in (it didn’t display anymore characters after the first parenthesis). Is there any way to get the plug-in code to recognise the ascii character code instead of the font symbol?

Thanks in advance for your help.
