Unicode Support for URL


Post Title, Page Title and Tag Slug with Unicode characters are converted auto-generated URL to garbage. Example:
Title - ঘোষ্ট একটি শক্তিশালী প্ল্যাটফর্ম
(Meaning: Ghost is a powerful platform)
Auto generated slug - ghosstt-ektti-shktishaalii-plyaattphrm
Slug should be like - ঘোষ্ট-একটি-শক্তিশালী-প্ল্যাটফর্ম
How can I change it to like this? Is there Unicode support for URL in Ghost?
