It seems pretty good; I just don't know how it would be used for dialogues in different languages.

It’s easy to add different languages to it. Instead of using strings directly, you just use variables.
For example, in my games I usually have all the text of the game in different languages in a csv file and load it from there to variables that I use with this dialogue engine. You can probably find more info about it in the internet.
