well, as far as i know i never opened it, but can try again and see.
I'll take a peek at it on hex editor to see how the symbol behaves.

err...i did open it but never modified or saved it.
weird though, it seems to work now if just extracted, not saved, and the weirder part is that i tested saving it on hex editor and checked afterwards that the hex for the symbol didn't change from unicode to standard so it should have worked... it didn't -.-

oh well, I'll just change it to [notices] :P

on a semi related note.. have you ever tried taking a peek at ps3 sprx files ?
I've now rebuilt every rco from flash0 and i can't seem to find the main icons of XMB anywhere. thre's no icons, and no default p3t themefile either....
they might be in prx's or then there's something else going on here. The prx's also contain attributes for certain things in XMB such as image dimensions and movement, spacing, scroll and whatnot settings of icons which i'd love to get my hands on.

i can provide you with 3.55 decrypted prx's if you need some and are willing to take a peek
