Slug generation for title with non-ASCII characters

If the title contains non-ASCII characters, SublimePelican's slug generation just omits these non-ASCII character.
If the title is full of non-ASCII characters (say, a Chinese title), the generated slug would be an empty string.

Pelican transforms non-ASCII characters to ASCII ones with unidecode module.
However, I tried using iki/unidecode@7b3e322 but it doesn't seem to work in Sublime Packages environment... :(
