Transcription from Pashto

From where I could copy/paste a letter similar to that:
š, but the one I need must be with a dot underneath.
I have all characters except that one. BTW, this character is sometimes used to transcribe ښ

Finally I've found this character. I am posting it here in case someone may need it in the future. This character is used to transcribe ښ .
