I'm currently working on a project involving filling the address book of an iPhone. One requirement of this task is that the address book is filled with random UTF-8 characters. However, some of these appear as an 'alien-head' or '?' (Sorry I need 10 rep to post a picture of them T_T).
Has anyone either found a way to recognise which characters cause this, or know of a CharacterSet of iPhone displayable unicode characters?
Thanks
