Sublime Text 2 allows you to write your own custom build system. The docs can be found here.

But when you have unicode characters in your cmd, you will get error, for example:

Marked.sublime-build:

{
  "cmd": ["open", "-a", "Marked", "$file"],
  "selector": "text.html.markdown"
}

Now if you have unicode in your file name, you will get such an error in your console(View -> Show Console) during building:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 0: ordinal not in range(128)

The stack traces into:

~/Library/Application Support/Sublime Text 2/Packages/Default/exec.py

line 130

129        if not self.quiet:            
130            print "Running " + " ".join(cmd)
131            sublime.status_message("Building")

It’s the print line causes the error. Patch this line will make everything smooth:

130            print "Running " + cmd.__str__()
