Description

The JsonMapObjectReaderWriter class maintains a list of ESCAPED_CHARS which includes special characters that need to be escaped like the newline (`\n`) and tab (`\t`) characters. This list also includes `\h`, but I can't find any links to official documentation about this character needing to be escaped. 

According to this SO post which details escaped characters in JSON, it does not include `\h` in this list.
