[racket] east asian characters were broken when I run from an Executable file

hello~!

I'm using DrRacket for Scheme Programming.

for I'm not a person who use native English, I need to print out east asian
language.

there is no problem when I press run button in IDE.

east asian language is printed well.

but when I make an Executable file, and execute, east asian characters were
broken when program prints out.

is there any way to solve this problem?
