To prevent implementation differences from creating a different event ID for the same event, the following rules MUST be followed while serializing:
- No whitespace, line breaks or other unnecessary formatting should be included in the output JSON.
- No characters except the following should be escaped, and instead should be included verbatim:
- A line break, `0x0A`, as `\n`
- A double quote, `0x22`, as `\"`
- A backslash, `0x5C`, as `\\`
- A carriage return, `0x0D`, as `\r`
- A tab character, `0x09`, as `\t`
- A backspace, `0x08`, as `\b`
- A form feed, `0x0C`, as `\f`
- UTF-8 should be used for encoding.
