Adding Greek Text to Icons in PS

I checked the memories pretty thoroughly but I might have missed the answer to my question. The only thing I could find that was remotely close was this about adding Chinese, Japanese characters to icons. I read over it but it didn't seem to apply. (Or I might just not be comprehending it to translate the applications from East Asian characters to Greek characters.)

I need to add the letters for a Greek organization to a few icons. I could just take it off their website and do a c/p job but it is harder to manipulate the text that way.

Is there a font for Greek characters specifically? Or is it just a matter of using a language switch in Word and then c/ping into a text layer in Photoshop? Or is it just using some better google-fu to find a Greek font? (My Google-fu is weak today, apparently)

I use Photoshop 6.0, US Full version. Any help would be really really appreciated. Thanks in advance. :)

ETA: I think it is solved. Thank you to everyone for their great help.
