That means the string you were trying to convert to latin2 contained 
characters which can't be represented in the latin2 encoding.

Most likely you specified an illegal string to start with ... the 
common mistake is to put non-ascii characters in a string literal ... 
literal strings of the form @"my string"  may only contain ascii 
characters so writing @"legyõz" would be illegal and would cause 
problems.

To get non-ascii data into a string, you could do something like -
NSData *d = [NSData dataWithBytes: "legyõz" length: 6];
NSString s = AUTORELEASE([[NSString alloc] initWithData: d encoding: 
NSLatin2StringEncoding]);

or you could encode it as unicode data in a literal propertylist string 
by using the \UXXXX convention to specify a sixteen bit unicode 
character as a using a hexadecimal value (I don't know the unicode for 
õ, but you see what I mean) ...

s = [@"legy\UXXXXz" propertyList];
