I'm trying to downsample a string to pure ASCII using the -[NSString
dataUsingEncoding:allowLossyConversion:] like this:
NSData *asciiData = [theString
dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
However, in some circumstances I get an exception thrown:
*** -[NSCFString dataUsingEncoding:allowLossyConversion:]: didn't
convert all characters
For instance, when I pass in the string "Det er gratis…" (the last
character is U+2026) it happens.
I'm not finding any documentation that it might throw an exception.
Isn't the point of passing in YES so that you can still get something
back even if not all characters are converted?
I tried a little test project with just this operation, and I didn't
get the exception. Any idea why it might function variably?
