Currently, the URL was formed based on what was typed as title for the post. It is not very user-friendly for people who write in other languages eg. Korean, Japanese and Chinese. The url will be invalid if the title was of another language. Hope that the next update would allow user to personalise the url (I don't mind if is some sequential numbering order, rather than a long string of text as url just because the title is long). Thanks!

Hi Dawn Ko,
Thanks for contacting us.
If the post title is not written in English letters (e.g Korean/Japanese/Chinese), our algorithm write the the word in English letters. So the url is always valid :)
Regarding your request to personalize the url - I've added it to our wishlist!
