Shall we say this is a change in behaviour and what happens?
| The Unicode character `\u0085` has been removed for unescaped identifiers and is now considered a whitespace character. | ||
| To continue using it, escape the identifier by adding backticks around it. | ||
| This applies to all unescaped identifiers in Cypher, such as label expressions, properties, variable names, or parameters. | ||
| In the given example, the quoted identifier would be \`my�identifier`. |

I think the dollar sign can stay to make it obvious what it is, I wanted the 0085 one changed because it didn't render to anything :)
