Hi Bug APL,

The spec for PNG says that the first byte for a PNG image has a value of 89.
When I read in a PNG, and I check the first value it is 137. When I ⎕ucs that, I get ‰

I tried copy and pasting, but it does not look like it displays in my mail client....Anyways it looks like a square box with "00" on top and "89" on the bottom. I guess this is the value I am looking for. however, this symbol is not equal to 89. What I am I looking at here? Is it possible to write this character, so that I can use it for checking if a file is a PNG?
