Json Charset Problem When Sending To Firebase From Js

I'm saving data to firebase RTDB through JS SDK (6.3.1) using: firebase.initializeApp(firebaseConfig); var data={ 'name':'Česká republika' }; var key = firebase.data

Solution 1:

This was in issue in a downstream dependency (the JavaScript minifier), which caused encoding problems on some edge cases.

The problem has been solved in version 6.3.4 of the JavaScript SDK, so I recommend upgrading to the latest version if you encounter this problem.
