Memory allocation?? Why? Real world, you'll bump into limits based on fonts long before you'll get a buffer that's too large for the stack and worth using the memory allocator for. I can't see any reason to support more than 2^64 characters and lots of headaches from trying to beyond that. You check your buffer writes and reject the character if it's too long.
