Is your feature request related to a problem? Please describe.
Given in title. It should be similar to how it already works for English. Currently if you give it text in other languages, the only output you could get is for numbers and English stuff.

Describe the solution you'd like
An option for the same. In case the app gets too heavy, give the user his/her choice for the languages they want to download and use.

Use case
To avoid effort. It takes too much more effort to type in other languages, which is exactly what this app can solve.
