Java Question SOLVED Passing String to lib saves with bad characters

If i pass a string to my library it encodes some characters bad:
This function saves a JSON file for library internal management, but inside some characters are changed like this:
The equal(=) symbol is changed to \u003d, in my lib the string is handled as Java String

I dont know if i need to set encoding or escape characters from B4A or from my Lib.

Help is very appreciated.

1. There is no difference between B4A strings and Java strings. The URL encoding happens somewhere else.
2. The less you do in the library itself the better. No reason to create a json string in your library code.

SOLVED:
Youre right @Erel, the string are passing as is without encoding from B4A to Lib.
The problem was the GSON function that saves the JSON with html entities encoded by default, it should be disabled on build:

The less you do in the library itself the better. No reason to create a json string in your library code.
