These are the strings written in framework-res as I remember.
It is possible to display non ABC letters there but I don't know if the current search engine will match letters with contact names. I used to play with this on MIUI GB.

Hi and thanks for the reply. Unfortunately the strings in framework-res are not corresponding to that ABC list found under contacts.apk. Back in Froyo (maybe in GB too) days i used to replace a png image. It could be some smali code now?
