There is a column 'asciiname' in the dump files. This is what you need. I just see it is missing from the web service result. Are you using the web services?
It seems you are using the web service without knowing it. The command 'placeNameSearchCallback' most likely calls our web service. Where have you got it from?
Normally it should be sufficient to ask for the English name (default). For 'Gujarat' we don't have many languages. Do you think the English name should be the ascii name? You can change it on our site, and if you are at it you could also add the Hindi name.
