GREAT !!!!
It worked like a charm. I write here just a brief for the Coca list and for
the memories. Suppose that strEncoding read is ISO-8859-1 (I assign it here
by myself).
strEncoding = @"ISO-8859-1"; NSLog(@"strEncoding %@", strEncoding);
CFStringEncoding cfEncoding;
NSStringEncoding nsEncoding ;
if(strEncoding)
{
cfEncoding = CFStringConvertIANACharSetNameToEncoding
((CFStringRef) strEncoding);
NSLog(@"cfEncoding %d", cfEncoding);
if(cfEncoding != kCFStringEncodingInvalidId)
{
nsEncoding = (NSStringEncoding)
CFStringConvertEncodingToNSStringEncoding
(cfEncoding);
NSLog(@"nsEncoding %d", nsEncoding);
urlText = [[NSMutableString alloc] initWithData:origData
encoding:nsEncoding];
NSLog(@"urlText converted is: %d", urlText != nil);
}
}
thus strEncoding was @"ISO-8859-1";
so cfEncoding = 513 which really is kCFStringEncodingISOLatin1
and nsEncoding = 5 which really is NSISOLatin1StringEncoding
The conversion of the NSString worked very well. Thank you again Scott.
Best Regards
