That is certainly possible. But as an old typist, I can tell you that the hands do the typing, not the mind. Your hands get into a pattern to use the lower case "l" key for a one and the upper case "O" key for a zero, and it is a hard habit to break just because you suddenly have a nifty, new typewriter with a "1" key and a "0" key...
But even more telling is that the typeface of that spurious "1" character does not match the typeface of the rest of the characters in the set. All the others have serifs while that "1" does not. A serif is the decorative grace line added to letters or characters such as the footer seen on this "1"—which actually are more than just decorations because they make it easier to follow a line of print. That "1" without the footer belongs to an entirely different typeface... which is a big red flag that the Australian BC is bogused up in some way and the forger made an error. The "1" that should have accompanied this typeface would have looked similar to the lower case "l" but would have had the slanted flag that IS on that "1".
I’m from Delaware and want to know where Castle stands on the issues especially after he screwed us all on cap and trade and I now have a feeling he is going to screw us on healthcare. The DEGOP wont help because they are 4 square behind him to either get re-elected to the house or win a Senate seat but if I search anywhere, its nothing but comments about the birther lady. Let it go birthers.
