OData: text fields are preceded by simple quote

Hi Guys,

I’m testing an OData API to communicate with Appsheet.
Since a little moment, I’m surprised to see that each Text fields are preceded by simple quote.
So when I’m debugging the variable a is content is reprensted by double quote + quote + text + quote + double quote.
And by the way data are stored as simple quote + text + simple quote in my database.

Previously, one month or maybe a little bit more, this kind of thing didn’t happen.

Do you know what’s causing this and if I’ve to modify my API to trim each simple quote for each text field ?
