SlugField and Slugify Problem

[Halit]

Hi.I'm creating to free time project on Django.

And,I'm using " SlugField " on my models.(to post url)

Also,I'm using " Slugify " template tag on my template.

If my title is = " Deneme Başlık", slug = " deneme-baslik "

But,if i use in my template to = {{ title|slugify }} = "deneme-baslk"

Delete to "ı" characters.This article has my problem(http://
