Sqlite: fetching fisrt char from the word and replace with * based on any condition : I need to fetch first char of contact names (includes all language) and replace chars which doesn't satisfy range of char-set for selected language.

For example:- My table will be having English contacts and Chinese contacts, now if I select Chinese language then my query should give me all the first chars from the names but for English contact it should return '*'. 

Any lead will be appreciated.
Thanks in advance.
