You'll almost certainly find that the 0 you think is there is actually a Q - try it and see.
0xC004F050 usually means that you've misread a character - either
C/G/6 or B/8 or
Y/V are the most common, an
O/0 is almost always a Q
Note that the following characters cannot be used -
A E I L N O S U Z 1 0 - so don't bother trying unless you like the noise it makes :)
