Strange Characters in JSON returned string

[fioranosnake]

You read a file, which has a UTF8 encoding with Byte Order Mark: EF BB BF

Use as encoding utf-8-sig when you read the file.
Then the BOM is stripped away.

The prefix \uxxxx is just a representation for Unicode code points in Json and also for Python.
What you see, are the first three bytes, which defines the Byte Order. Usually this is not used.
I guess you must seek for documents, which are still using the Byte Order Mark.

Perfect Thank You!!!
