Hi again
Ok, I think it will work, but I do have a last newbie question to ask
if I can...
I've managed to convert from the UniChar result to an NSString, but I'm
not clear on how to efficiently do the reverse. My original string is
in an NSString and I guess I need to convert it to UniChar... but being
pretty unexperienced, this looks like a mystery to me. Do I need to
iterate through each character using characterAtIndex and add them to
characters[] one by one? Should I use an NSScanner? Is there an
immensely obvious way to do this and I'm just not seeing it (probably).
I now its probably something I should know, but considering I've only
been programming for a year or so except for stuff like AppleScript, I
miss a lot of things.
My current idea is a for loop using characterAtIndex to add each
character...
Thanks for your time if you can afford it.
