Yes they can... look into patch, you see some lines not only beginning with 490xxx but with 48Bxxx. These positions can be found with CE.
Here the way: Click the first "N" (normal font), then 6 times page down and you see greek symbols and the phone symbols. The rest is same as before.
If you have some nice changed symbols, you could show them to us (by attaching the created .vkp files).
