Specials char while adding items

[pINKmUNster]

Hello,

do someone know how to manage specials chars while adding items into a listitem?

I'm doing stuff like this :

// Fill a dictionary with fields and their value
Dictionary<string, object> item = new Dictionary<string, object>()
{
    { "Chargé", "Item1" },
    { "Field A", 25 }
};

// Persist the item
var addedItem = await myList.Items.AddAsync(item);

And i'm facing a 400 issue

HttpResponseCode: 400
Code: System.ArgumentException
Message: Column 'Chargé' does not exist. It may have been deleted by another user.  /sites/*/Lists/List

Thank in advance

@pINKmUNster : can you confirm you've a field with internal name Chargé in your list?

@jansenbe No, i have Charg_x00e9_ , if I understand well I need to use the internal name instead of the title , to add or update items in a list item?
