//  It's best not to use non-usascii literal strings in source code.
//  Instead, use a binary encoded representation of the string.

//  This is the string "44ης Οδός, αρ.2" encoded as quoted-printable.
//  Use Chilkat's online tool to prepare encoded strings: Online Binary Encoder
//  Note: For strings that have very few us-ascii chars, it's better to use base64 encoding instead of quoted-printable.
NSString *s = @"44=CE=B7=CF=82 =CE=9F=CE=B4=CF=8C=CF=82, =CE=B1=CF=81.2";
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];
[sb AppendEncoded: s encoding: @"quoted-printable"];

//  For programming languages where strings are exposed bytes, you can tell Chilkat globally
//  to give you the utf-8 byte representation.
//  For programming languages where strings are opaque objects, such as C#, it doesn't matter.
CkoGlobal *glob = [[CkoGlobal alloc] init];
glob.DefaultUtf8 = YES;

NSString *s = [sb GetAsString];
