Receiving "Unable to parse JSON - Unrecognized character escape" on query string value with backslash

Passing to query string parameter value (URI encoded), e.g. "F\p" and while processing this string in validator I get exception:

[ERROR][REQUEST][GET /objects @query.param] Unable to parse JSON - Unrecognized character escape 'p' (code 112) at [Source: (String)""F\p""; line: 1, column: 3].

Schema for this param is:

      parameters:
        - in: query
          name: param
          required: false
          schema:
              type: string
              minLength: 1
              maxLength: 20
              nullable: false

Expected behaviour:

param value is accepted without problems

Note:

exception is not thrown for specific backslash combination with specific meaning like "\b, \d, \n, \r, \t, etc." but probably theirs meaning is changed during parsing.
