Escape sharp character

[s-celles]

Hello,

I have the following sequence diagram

sequenceDiagram
    participant M as PC (Maître)
    participant E as ATmega16 (Esclave)
    
    rect rgb(200, 255, 200)
        Note right of M: Cas normal
        M->>E: TEMPERATURE\n
        E->>M: VALEUR XXX\n
        Note right of E: XXX = valeur entre -99°C et +999°C
        M->>E: OK\n
    end
    
    rect rgb(255, 220, 220)
        Note right of M: Cas d'erreur
        M->>E: Commande non valide\n
        E->>M: ERROR\n
        Note over M: Recommence<br/>la procédure
    end
    
    Note over E: Retour en attente d'une nouvelle requête

I would like to have #TEMPERATURE\n, #VALEUR XXX\n, #OK\n and #ERROR\n displayed.

I can't escape sharp character (or I don't know exactly how to proceed.

Some help will be nice.

I ever tried \#..., "#...", '#...' but none seems to work

Best regards

It may have already been solved, but for those who encountered the same problem.
#35; is the solution.

Is there a reason why mermaid syntax for escaping characters is slightly different than HTML?
In HTML you would write # to get #, works in Mermaid with #num; AND #
As an alternative in HML you can write # to get #, but in Mermaid you have to write #35; and # will be rendered as &#. This is confusing. Especially when you programmatically generate mermaid syntax you are tempted to use a HTML library that does the escaping which obviously doesn't work.
Any reasons for this unnecessary (?) custom syntax?
