er does not support UTF-8

[pajaro1966]

Description

When I use UTF-8 characters not used in English, graph does not get rendered. I've tried with different versions (10.9.1 and 11.0.2). If I write "categoria" (I without accent), the graph is rendered:

But if I write "categoría" (with accented í), the graph doesn't get rendered:

It is not possible to use different alphabets different from Latin (e.g. Greek) in the atttributes. Only in the title (if using " ") and the comments (because you have to use " "). There seems to be a problem with UTF-8 implementation.

All that said, I think Mermaid is really great. Thank you for developing such an amazing tool!

Steps to reproduce

1. Paste this code into Mermaid Lice:
   erDiagram

    "πειστικός" {
   

string sufijo "ικός, ή, όν"
integer acento "1"
string categoría "adjetivo"

}

2. The graph is not rendered.

I can confirm this, maybe it could be solved allowing to pass in a quoted string as well (like in the comments).
dupe of #4339
imho interferes with #5123

This issue also prevents the use of emoji in ERDs. For example, it would be really helpful to be able to do something like this:

erDiagram
    CUSTOMER ||--o{ ORDER : places
    CUSTOMER {
        int "🔑id"
        string name
        string custNumber
        string sector
    }
    ORDER ||--|{ LINE-ITEM : contains
    ORDER {
        int "🔑id"
        int orderNumber
        string deliveryAddress
    }

#625 is closed, but it really shouldn't be because multiple other diagram types do not properly support emoji/UTF-8.
