If the iPad is anything like the Macintosh, it will probably use the Option key as described on this page: Macintosh Accent Codes. I'm glad you asked the question, magimag, because in the course of looking for an answer I found out about several Windows key combinations which I hadn't come across before!

Or you can always bring up your character map from windows and copy and paste from there. A little more long winded though.

the reason older photos enlarge better than digital ones is digital ones resolution is not as good even as 35mm film ,some of the older pics were even the same size as the negatives (contact prints) and the quality of an enlargement depends on grain size or in digital pics pixel size in both the more you have to enlarge a pic the grainier it is henc a contact print can go a long way before you see the grain ....hope thats as clear as mud
