The initial string is UTF8.
You're recreating it from the db using this
[ArrFav addObject:[NSString stringWithFormat:@"%s",str]];
which is just converting str
with naive ascii (the %s
format specifier)
Try this instead to force it to use UTF-8 to decode the string :
[ArrFav addObject:[[NSString alloc] initWithCString:str encoding:NSUTF8StringEncoding]];
Here's it the simplest solution, if you've only worried about •
symbole.
//Convert • symbole with some different symbole that SQLite DB allowing
- (NSString *) convertToDBFormat:(NSString *)str
{
NSString *temp = [str stringByReplacingOccuranceOfStrings:@"•" withString:@"!~!"];
return temp;
}
//Convert back to origional format after retrieving from SQLite DB
- (NSString *) convertBackMyFormat:(NSString *)str
{
NSString *temp = [str stringByReplacingOccuranceOfString:@"!~!" withString:@"•"];
return temp;
}
Instead of !~!
you can use any symbol which is not part of your string! :)
