utf8 characters in custom url scheme

I made a custom url scheme.

when the keyword is in English it's OK.

NSLog :

myscheme://withkeyword/?keyword=english

When the keyword is in Korean, in Japanese etc, look like the below.

NSLog :

myscheme://withkeyword/0.000000keyword=2.122748E-314D99C3.246487E-314AB88

What's wrong?
