@paul (and anyone else who is interested).
To enter strange punctuation in this forum you can use what are known as HTML entities. Copy the characters to the right of each symbol and remove the underscores before pasting into a post.
© = &_copy_; ¼ = &_frac14_; ½ = &_frac12_;
There's more examples in the "Not an entry just playing" thread.
There's a full list of HTML entities here:
