your korean encoding transformation is only happening in debug here (check line 383)
I think what you want is to do it always and transform the resp.Body if the option for euckr response is enabled

That's right, actually I'm using the client in typescript, and the library is already encoding and transferring body values normally

I'm not used to golang because I don't use it professionally
As you said, if the euckr option is enabled, it should always be reflected in the result

@bogdanfinn Of course, https://helinox.co.kr

wr := transform.NewWriter(&bufs, korean.EUCKR.NewDecoder())
wr.Write(buf)
wr.Close()
finalResponse = bufs.String()

It's a log to check if it's encoded normally
