Sure. transliteration.dat is one of the datasets used by libpostal to parse addresses. For illustrations of what does it do, go to https://github.com/openvenues/libpos...les-of-parsing and scroll down to normalization as well.

fun fact: OSMSS was, to my knowledge, the first on mobile to use this library.

we use libpostal as a core for geocoder - the library that finds coordinates on the basis of your string. out of these datasets used by libpostal, transliteration is, as far as I can guess, used to make from Привет to privet. As a result, you can search for addresses even if you don't have the same chars on your keyboard.


Issues are many:
