The Common Way Of Making Game Localization N Unity

I'm making a game that require localization(change from one language to another language) what is the common way of doing it?

 

There are two ways that I know but maybe there are some smarter ways to do it, so I wanted to ask people actually starting doing any code

 

1.Use a plugin in Unity called I2

2.Use XML and translate it manual
