json string decoding encountering invalid escape

Question

I am using simplejson to decode the following json string.

Here is a demo written in Python:

from simplejson import loads

loads("""["s"]""")

The decoder will throw:

JSONDecodeError: Invalid escape

How to cope with this? The expected output is:

["\s"]

Answer 1

"s" is not a valid JSON escape string.

According to json.org, only the following escape are valid

• "
• \
• /
• f
• u four-hex-digits
