Build broken issue during compiling less files with system locale setting as Korean, Japanese and Chinese

[ahwizzang]

I'm having problem for compiling less files when I set my 'current language for non-Unicode programs' setting as Korean, Japanese or Chinese(I guess there should be more languages which occurs this problem). I got error message like this.
