If you can't, it's big trouble for Texinfo's Unicode support for luatex. Do you know of any way to go back to byte-wise input instead of input by UTF-8 characters? Also I'm not sure in this case if it's 0xC2 that's active or the whole character 0xC2 0xA7. Do you know if each UTF-8 character has its own catcode?
